HTU21DF Waterproof Anti-condensation Capacitive Digital Temperature Humidity Sensor Chip

Overview:

The HTU21DF is a waterproof and condensation-resistant capacitive digital temperature and humidity sensor chip manufactured by Humirel, a brand under TE Connectivity. Housed in a miniature DFN package (3×3×0.9mm), it is ideal for space-constrained OEM applications.

Features:

1. Digital Output:
   Adopts I²C digital interface, providing calibrated and linearized temperature/humidity signals for direct connection to microcontrollers.
2. High Precision:
   • Humidity accuracy: ±3%RH; temperature accuracy: ±0.3°C.
3. Wide Operating Range:
   • Temperature: -40°C to 105°C; humidity: 0 - 100%RH; storage temperature: -40°C to 125°C.
4. Low Power Consumption:
   Suited for battery-powered devices and applications with strict power constraints.
5. Fast Response:
   Quickly reacts to environmental changes with minimal temperature effect.
6. Condensation Resistance:
   Recovers measurements within 10 seconds in dew-point conditions, adapting to harsh environments.
7. High Compatibility:
   Pin-to-Pin compatible with Switzerland's SHT20/SHT21 in hardware, and software programs can be replaced directly.
