Simply connect the red wire to 5V power, black to ground, yellow wire to your i2c data pin, and the white wire to the i2c clock pin. You cannot change the i2c address so only one sensor per i2c bus. Two ~10Kohm pullup resistors are required for use, connect from the SDA and SCL lines to the power wire, the pullup resistors are not included!
We don’t have a detailed tutorial at this time but you can find our example library for Arduino that does temperature/humidity readings at our github repository.
- 3.5 to 5.5V power and I/O
- 10 mA max current use during conversion (while requesting data)
