I have a need to monitor and log temperature and humidity in several places in my house and I have wired up 3 AM2302 DHT sensors in the attic.
But now I also need to connect to a few extra sensors that cannot be wired in to the ESP-07 unit, so I cannot use the DHT sensors. So I figured that if I use commercial wireless sensors operating on 433MHz it could be possible to connect to them and read the data over 433MHz.
Is there some libraries for 433MHz receivers (note: I am not looking for transmitters) that can be used for ESP8266?
And are there any tutorials for that kind of project?
I assume there are two different steps that need to be taken:
- Connecting a 433MHz receiver to the ESP8266 to get the digital data stream
- Decoding the incoming data to extract the wanted information (temperature and humidity)
Grateful for any suggestions!
