The HTU21D is a low-cost, easy to use and highly accurate digital humidity and temperature sensor. It provides calibrated, linearized signals in digital I2C format. It is a sensor designed for volume and cost sensitive applications with tight space constraints.
- No calibration required (standard conditions)
- Typical humidity accuracy of ±2%
- Typical temperature accuracy of ±0.3C
- I2C interface
- Home appliance
Adafruit have developed a library for the HTU21D sensor that you can find in their GitHub repository.
