Description
The HTU21D Temperature and Humidity Sensor Module is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. It is used for environmental sensing and data monitoring with just two lines of I2C communication., perfect for weather stations.
There are only four pins that need to be hooked up in order to start using this sensor in a project. One for VCC, one for GND, and two data lines for I2C communication. This breakout board has built-in 4.7k pull-up resistors for I2C communications. If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors. The measured time of this sensor is up to 50ms.
Features
- Uses the I2C interface
- Typical humidity accuracy of ±2%
- Typical temperature accuracy of ±0.3C
- Operates from 0 to 100% humidity but this sensor isn’t recommended for harsh environments where it could come in contact with water (such as rain).
