MEAS HTU21D SENSOR FOR GROVE SYSTEM Digital Humidity and Temperature Sensor The HTU21D provides the necessary hardware to interface the HTU21D digital relative humidity and temperature sensor to any system 2 that utilizes Grove compatible expansion ports configurable for I C communication. The HTU21D sensor is a self-contained humidity and temperature sensor that is fully calibrated during manufacturing. The Performance sensor module works in 5V external, and the sensor has selectable 0% to 100% relative humidity range resolution, low battery detection, and checksum capability. The -40C to 125C temperature range HTU21D has a low power stand-by mode for power-sensitive Very low power consumption applications. Operates in 5V. Fast response time 5 seconds typical Built-in heater for fast recovery from saturation Specifications Recovers fully from condensation Measures relative humidity from 0% to 100% Fast conversion time 14ms typical Measures temperature from -40C to 125C 2 I C communication Fully calibrated Fast response time Selectable resolution Very low power consumption Features 4-pin Grove compatible connector 2 I C interface Selectable 8-12 bits resolution for humidity Selectable 11-14 bits resolution for temperature SENSOR SOLUTIONS /// MEAS HTU21D FOR GROVE SYSTEM 06/2017 Page 1 MEAS HTU21D FOR GROVE SYSTEM Digital Humidity and Temperature Sensor Schematic 2 Connector Pin Assignments (I C Communications) Dimensions (mm) SENSOR SOLUTIONS /// MEAS HTU21D FOR GROVE SYSTEM 06/2017 Page 2
