Cheap temperature/humidity sensors to home server

2021-02-08 18:18:54.379962+01 by Dan Lyke 0 comments

Mark VandeWettering has been playing around with some temperature and humidity sensors, which he's described on Facebook, and I'm intrigued.

Nooelec NESDR Smart v4 Bundle - Premium RTL-SDR w/Aluminum Enclosure, 0.5PPM TCXO, SMA Input & 3 Antennas. RTL2832U & R820T2-Based Software Defined Radio.

Ambient Weather F007TH Wireless Thermo-Hygrometer for WS-07, WS-08, WS-10, WS-11, WS-110, WS-70 Weather Stations.

Reception is done via rtl_433M, and Mark says:

To send the data to my MQTT server, I just run rtl_433 -F json and then pipe it to mosquitto_pub. Then I have a nodered server which can subscribe to the mqtt data and send it to my influxdb server, which grafana can graph for me.
