This gist provides a script for logging temperature and humidity using a DHT22 sensor and the Riffle-ito data logger.

Required Libraries

• JeeLib
• DHTlib
• RTClib - mizraith’s fork of Jeelab’s RTClib that includes support for DS3231.

Hardware Setup

DHT22 connected to Riffle-ito with red wire to 3.3v, black wire to GND, yellow wire to A1 pin

Optionally, connect LED to pin A2 and GND (with resistor, see blink).
