Product Description
The HTU21D Temperature and Humidity Sensor Module is a high-quality, low-cost, easy-to-use sensor that measures both humidity and temperature with high accuracy. It is suitable for environmental sensing and data logging applications, such as weather stations or humidor control systems. It uses I2C communication protocol, which requires only two data lines to connect to the sensor. The measurement time of this sensor is up to 50 msec.
This breakout board has four pins: VCC, GND, and two I2C data lines. It also has built-in 4.7k pull-up resistors for I2C communications. If you have multiple I2C devices on the same bus, you may need to disable these resistors.
Note:
Full drops of water can damage the sensor. We recommend wrapping the board in Teflon/irrigation tape for extreme conditions where water droplets may find their way into the sensor.
