- 100 nA Sleep Mode Current
- Average Supply Current:
- 710 nA @ 1sps, 11 bit RH Measurement
- 1.3 µA @ 1sps, 11 bit RH and Temperature
Measurement
- Supply Voltage 2.7 V to 5.5 V
- Small 3 mm × 3 mm Device Footprint
- I2C Interface
The HDC1050 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The HDC1050 operates over a wide supply range, and is a low cost, low power alternative to competitive solutions in a wide range of common applications. The humidity and temperature sensors are factory calibrated.
