AM2315 – Encased Temperature / Humidity Sensor
Out Of Stock
Looking for a nice enclosed temperature and humidity sensor? The AM2315 is effectively a DS18B20 temperature sensor and a capacitive humidity sensor in a nice enclosure. The enclosed sensors are much better suited to sensing in areas exposed to wind / rain / snow than a breakout board or bare sensor. A small microcontroller inside does the readings and provides a simple I2C interface for reading the finished & calibrated output data.
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 can be used 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 with the sensor.
- 3.5 to 5.5V compatible
- 0-100% humidity with 2% accuracy
- 0.5 Hz update rate
- Body: 98 x 16mm diameter (4 x 0.9″)
- 10 mA max current use
- -40 to 80°C with ±0.1°C typical accuracy
- 4 wires 20 inches long
- Uses I2C 7-bit address 05C
