The HTU21D Click Board is a high-precision measurement add-on board that gives an easy way to add a humidity and temperature sensor to your design. The board includes easy-to-use, fully calibrated humidity and temperature sensor to develop reliable environmental sensing nodes. The measurement range of HTU21D click is from 0 to 100 percent for relative humidity. For temperature, the measurement range is from -40 to +125 degrees Celsius. HTU21D click uses mikroBUS I2C lines (SCL and SDA) to communicate with the target board MCU. It is designed to use a 3.3V power supply only. Featuring a plug and play design, it requires no calibration to use. The default resolution of the signal is configured to 12-bit for relative humidity and 14-bit for temperature readings. HTU21D click is designed to use a 3.3V power supply.

It is a reliable choice to develop environmental applications such as data logging, a weather station, and temperature and humidity control in HVAC systems.

Adjustable signal resolution

The default resolution for relative humidity and temperature readings in HTU21D click is set to 12-bit and 14-bit, respectively. However, the humidity resolution can be arranged between 8 and 12 bits, and temperature resolution between 12 and 14 bits.

Tip on Sensor Placement

It is important to place HTU21D click at a place where it can get a correct ambient temperature reading, since relative humidity is dependent on temperature. Don't place the sensor right next to the heater in a closed space, or next to a hot metal railing in the veranda. In simpler words, don't place it next to something that is hotter or colder than the environment.
