WiFi Sensor 1

This sensor uses an ESP8266 Wireless chip directly connected to a DHT22. Its currently being tested for consistency and stability. The intention with this sensor is to be a low power sensor that I can run from a battery (I am planning to use a 18650).

Hi bluestreak, nice project. Have you found the DHT22 to be stable? Are there data spikes? If so does your code do any filtering? The data shown looks averaged.

Hi, Sorry for such a late response I only just saw this hiding at the bottom!
I do on occasion see a weird result/spike but out of the year or so I've had it going for its happened maybe 5 times at most and for the low cost its pretty stable.
No averaging data is passed straight from the DHT on to here. I'm actually going to simplify the project now and make the sensor read only so it listens for a request instead of pushing out the data. That way I can mass produce them and only have to set the wireless details. I'll have a server that would store the data and maybe push it to Thingspeak but I'm using this platform more for testing.
