ESP8266 & DHT22 Lowpower MQTT Sensor
For my project where I control my remote via pnps I want to create a low power sensor which will be able to send humidity & temperature data to my openhab server which is running mosquitto
Since I have some esp8266 chips laying around, this would be great to setup as a wifi mqtt sensor with the dht22, which will periodically (every 10 minutes) send new sensor data to my mqtt broker.
A quick video how to get a basic breadboard setup:
I will need it to be pretty energy efficient, so whenever the esp is done sending data, it will go into deepsleep for 10 minutes, and then wakeup and send again…
