Low power wireless temperature and humidity node
V2.0 hardware revision adds support for SI7021 temperature and humidity. This sensor brings performance and power savings over the DHT22, see sensor folder of this repo for sensor evaluation and comparison.
The emonTH V2 is an open-source, wireless, battery powered temperature and humidity monitoring node.
Data from the emonTH is transmitted via wireless RF (433MHz) to an emonPi / emonBase web-connected base-station for logging to Emoncms for data logging, processing and graphing.
