Room Board plugs Based on the time-proven "hot-wire"

Based on the time-proven "hot-wire" method

but omits the HYT131 sensor module

Or you can solder the board directly in place for more permanent use

where the spinning cup anemometers are ineffective

Note:  Just like the Arduino

Room Board plugs Based on the time-proven "hot-wire"The Room Board is a small board with sensors for indoor monitoring of several environmental parameters: temperature via either an HYT131 or a DS18B20 humidity via the same HYT131 sensor motion via a passive infrared detector (PIR) light via an LDR Different configurations are supported include omit the relatively expensive HYT131 or include omit the motion sensor. The configuration is adjusted by selecting the 1 or 2 resistors to add (not included in
