Smallish Temperature and humidity sensor. This is my first go at using the MySensors.ORG code for distributed networking sensors and while still trying to get my head around the whole thing this is the first sensor I've put together that I can drop anywhere around the house and receive updates in my Home Automation server. Nothing really ground braking here but, just packaged slightly different to the normal stuff I've seen around the place. This is only a first go at this and I'm interested in seeing how long this will run for on a pair of AA batteries without any modifications to the Arduino to reduce it's power consumption, so far i'ts only been running for 5 days. The parts for the project are as follows. 1 x DHT22 Temp and Humidity sensor 1 x Arduino Pro Mini 3.3v/8MHz 1 x NRF24L01+ 2.4GHz Transceiver 1 x 4AA Battery holder with integrated on/off switch Here is a photo of the packaged, I think it looks relatively neat, colour isn't the best
When it's worth engineering, it's worth over engineering.
