esp8266 tft lcd weather station quotation

In the previous article (“WiFi OLED Mini Weather Station with ESP8266“) I have used the OLED kit from https://blog.squix.org. And as promised, this time it is about the “ESP8266 WiFi Color Display Kit”:

I had ordered both because I thought that the Color Display kit is needs the other kit as a base. Well, it turned out that both kits work independently. My bad. Actually this is good, as I have now two independent ESP8266 weather stations :-). An addition to that, they can exchange data (e.g. temperature/humidity) with a server, so that makes them a perfect dual weather station.

Example code is available on GitHub (https://github.com/squix78/esp8266-weather-station-color). The code is very well documented I had no issues to make all the needed configuration (WiFi SSID and connection settings). After a few  hours I had the ESP8266 weather station up and running in the first prototype of the enclosure:

After a few hours, I have now my second ESP8266 WiFi weather station with touch LCD. It is not looking good and I very much enjoy it. The design is available on Thingiverse (https://www.thingiverse.com/thing:2527282).

Welcome to my new Weather Widget Project. Earlier I have posted an article on the weather widget, that uses a 0.96" OLED display to display the weather parameters. The main problem in the earlier version is that the display is very small in size, so you have to come very close to it for reading the parameters. That"s why it was always in my mind to upgrade it to a larger color display with a nice 3D printed enclosure.

In this post, I will show you how to make a Weather Widget by using ESP8266 and a 2.8" touch screen display. The device retrieves localized weather information from https://openweathermap.org/ by WLAN and displays it on the Display module.

I would like to give credit to my friend Dani Eichhorn who did all of the programming parts. He is updating the software on his Github page regularly with new features. You can visit SquixTechBlog to see more projects on ESP8266.

My plan is to place the weather display circuit inside a 3D-printed enclosure. But the enclosure that I am going to use is very compact, and there is little room to keep the Wemos board along with the connecting wires inside the housing.

The wiring diagram is very straightforward. You have to connect the TFT display module ( ILI9341 ) pins with Wemos pins as per the schematic diagram. The schematic diagram is shown above. You may also follow the following pin mapping

2. Enterhttps://arduino.esp8266.com/stable/package_esp8266com_index.json into the File>Preferences>Additional Boards Manager URLs field of the Arduino IDE. You can add multiple URLs, separating them with commas.

After setting up Arduino IDE and installing all the libraries we can move to upload the code into the ESP8266 board ( Wemos D1 Mini Pro or any other board )

First, you have to unzip the code downloaded in the earlier step and then save it somewhere on your PC or Laptop. Remove the word master from the folder name, the final name shall be " esp8266-weather-station-color "

In one of the tabs, the IDE opened settings.h. Go through the file and adjust the two handfuls of configuration parameters. They are all documented inside the file directly. Everything should be self-explanatory. Most importantly you will need to set the OpenWeatherMap API key you obtained in a previous step.

If you are successfully uploaded the code into the ESP8266, you will immediately notice the display on the front page by searching the WiFi Network for connection. After connecting the device to your WiFi router, it will update the time and weather data from the web.

Now you will be able to see all the weather information along with all other parameters on the TFT display. You can swap between the different pages by using the stylus or touching with your finger.

As you all know the are a few variants of the 1.8" TFT on the internet. With the genuine Adafruit lcd-s there are usually no problems. But when using fake ones(usually from Aliexpress) you have to make some adjustments.

Bodmers TFT_eSPI library is very awsome and rich funcionality. And the best part is that he made it to handle the pixel offsets depending on wich kind of 1.8" TFT you are using.

Then uncomment the tft height an width. And then in my case(REDTAB) uncomment for eg: #define ST7735_REDTAB. After this save it for the moment and compile sketch and upload to board. To be sure i have defined the parameters in the sketch too.This is a bit long procedure, cause you have to compile and upload the sketch every time to board untill the offset is gone, but it is worth the experimenting. For editing the h. files i strongly suggest Wordpad. Images included.

The project gets the weather forecast from the openweathermap.org website. In order to parse the weather data we need the excellent Arduino JSON library. We also need two libraries for the display.

Let’s see the code now. At first, we have to set the SSID and the password of our WiFi network. Next, we have to enter the free APIKEY from operweathermap.org website. In order to create your own API key, you have to sign up in the website. Getting current weather data and forecast is free but the website offers more options if you are willing to pay some money. Next, we have to find the id of our location. Find your location and copy the ID which can be found in the URL of your location. Then enter your city’s id in the CityID variable. The last step is to enter your time zone in order for the project to display the correct time. Now we are ready to move on.

At first, we connect to the WiFi Network. Then we request weather data from the server. I only request one result, the weather forecast for the next 3 hours. You can easily modify the code to get more forecast results if you wish. We get a reply with the weather data in JSON format. Before sending the data to the JSON library I manually delete some characters that were causing me problems. Then the JSON library takes over and we can easily save the data that we need in variables. We have to take a look at the structure of the JSON data that the openweathermap website replies to see how to get the data we are interested in. After we have saved the data in variables, all we have to do is to display them on the screen and wait for 30 minutes before requesting new data from the server. We display the time of the weather prediction, the temperature and the weather icon. The weather icons consist of some bitmap graphics and some simple shapes. I have also prepared a version of the code which displays the temperature in degrees Fahrenheit.

In this project, you’ll learn how to build a Weather Station Interface PCB Shield for the ESP32 development board. The PCB features a BME280 temperature, humidity and pressure sensor, a light dependent resistor, a pushbutton, an OLED display and multiple WS2812B addressable RGB LEDs. The OLED displays the sensor readings and the LEDs produce different lighting effects to what is shown in the OLED. It also displays date and time.

We were playing around already with LED MATRIX’s, devices to visualize measured values and/or texts. In this blog post (Tutorial) we will use a TFT Display (Thin-film-transistor liquid-crystal display) with touch screen to display a three (3) days weather forecast with moon phases. This little weather station acquires its data over a Wi-Fi connection from an online weather server,

We will use devices from ADAFRUIT; they have developed a special product series for easy mounting, the FEATHER series. We need the TFT FeatherWing – 2.4″ 320×240 Touchscreenand theADAFRUIT Feather HUZZAHwhich has included anESP8266.We used theESP8266already in our previous blog post<===><===> so we are already familiar with its use!

There is some preparation needed before we can test our code for the weather station: I suggest that you read and that you follow each step as shown in this tutorial by ADAFRUIT (very important, otherwise it won’t work!!):

When it doesn’t work, you won’t GET an internet connection, thus meaning that you see on the screen “Internet Connection” for a loooong time, without that the weather data gets shown, you didn’t follow step by step the instructions!! Check our previous blog post (Tutorial) on How-To let the NEW device GET access to your Network:

i made a weather station which is build on a ATmega2560 mini pro, Esp8266 module which communicate with atmega on serial1 which sends values to thingspeak, an TSL2561, 2.4 tft lcd, BMP180, DHT22 and a dust sensor module PMS5003 which is set on serial3 on mega2560.

I made the wiring, program etc. the weather station is working fine for some days when it freezes. The problem is that thingspeak reports that it receive some data every 6 mins like i set it but the data received is blank. Not 0, or any other value, just blank data.

Atmega reads all values from sensors, then communicates with esp8266 by serial and using AT commands it sends the values read to thingspeak. So in my opinion it reads the values, but it won"t stores them, then it sending blank data to thingspeak.

I went and saw the station, it"s more like an electrical problem imo because if i reset arduino nothing happens. The data readed by arduino on dht22 is nan and the rest of the sensors is working fine. The only way i could make dht22 reading again is to unplug the power and plug it back. So that"s why i think it"s more an electrical problem but can"t figure why dht22 stops responding and need to switch off all power to bring it back to life. I will try putting an capacitor on wires to dht22 to see if it"s better.

I have an ESP8266 connected to a DHT11 temp/humidity sensor and an ILI9341 TFT-LCD screen to display the data I receive from the NTP server and OpenWeatherMap. I noticed that after a while of normal running it just resets due to what I believe is a shortage of memory (caused by OpenWeatherMap). I tried inspecting the error it gives when it resets and it has something to do with a "Panic" mode of the ESP8266"s, although I never managed to get a copy of what it spits out.

I"m asking this question because I"m planning to add a weather forecast section, but when I tried to add the piece of code needed to get the forecast data, it just crashed right off the bat everytime it turned on.

In this tutorial we will show how to build WiFi touch screen thermostat. ESP8266 WiFi touch screen thermostat is example of complex sensor build by ESP8266 EasyIoT Arduinolibrary. We will use Arduino Mega 2560 and TFT 3.2" touch screen display. You will be able to access and control thermostat securely from remote locations. Thermostat will also show some additional data, like outdoor temperature, air pressure and weather forecast.

This is easy, because we will use shield. Just put TFT 3.2" LCD Shield Expansion Board and 3.2" TFT LCD Module Touch Panel on top of Arduino Mega 2560.

In this case we will use HW serial1 to connect ESP8266 module. Follow Connenct 5V Arduino and ESP8266 tutorial to connect ESP module to Arduino. Arduino Serial1 RX pin is 19, Tx 18 and Reset pin is 12. For 3.3V power supply we will use 3.3 V from TFT shield expansion board. See picture below where to connect 3.3 V.

This is first version of thermostat. For future versions there is idea to add multiple zones to thermostat. Also display graphic design is basic. If we use SD card attached to TFT display we can create screens with nice graphic.
