Project to log room pressure temperature and humidity.
Hardware:
- ESP8266
- Particle Photon
- BME280 Sensor
- BMP280 Sensor
- 2x Raspberry Pi (Any above Series 2 should work, I used Rasperry Pi 3). One inside the room, and another outside. You can combine the work of two if need be.
- 2x Raspberry Pi Sense Hat (BMP280 can't do humidity, so I used two of these to get humidity measurements (ignoring the humidity measurements from BME280 for code symmetry).
- Power Supply for Raspberry Pi, ESP8266, and Particle Photon.
Communication between the Raspberry Pi and the microcontrollers happens through MQTT. Final Data is presented on a Node Red based UI.
