IoT Weather Station

Hardware

• MCU Wemos D1 mini
• absolute barometric pressure sensor GY BME 280

Software

• IDE of your choice (Recommendation is VSCode with Platformio) ## Dependencies
• Library for the temperature sensor by Adafruit(there are alternatives available though)
• Library for Pub-Sub over MQTT
• Library for the Air Quality sensor MQ135

Getting Started

• clone the code

foo@bar:~$ git clone [email protected]:MaiLinhGroup/iot-weather-station.git

• open src/main.h and replace the default values for WiFi with own WiFi credentials
• depending on which IDE (please check out the respective documentation), resolve the aforementioned dependencies, compile and flash the code to the board
• open a serial monitor, if needed set baud_rate: 115200 , and press the reset button on the MCU to reboot the MCU
• after reboot the MCU will display its IP address in the serial monitor, enter/open this address in any browser to see weather station information

Note

• idea for the project and great source of further explanation
• examples for ESP8266 with Arduino
