A weather station build around ESP32 with BME280, MQ135, and BH1750

Here we are USING MQ135 TO MONITOR AIR QUALITY. ALSO, USING ESP8266 TO SEND DATA TO THINGSPEAK .

Weather station using an ATmega2560 and ESP8266 Author: Nikola Bogdanov

This channel measures Temperature and humidity with a DHT22 and PM2.5 &10 with a SDS011. All with an ESP32, an MQTT and a Node-Red server.
