HTU21D Digital Humidity Sensor


Measurement Specialties plug-and-play transducers for OEM applications


Measurement Specialties HTU21D sensors are dedicated humidity and temperature plug-and-play transducers for OEM applications. Direct interface with a microcontroller is made possible as both the humidity and temperature sensor modules have digital outputs. HTU21D sensors feature low power consumption, and are designed for high-volume and cost-sensitive applications with tight space constraints. Every sensor is individually calibrated and tested. Lot identification is printed on the sensor and an electronic identification code is stored on the chip – which can be read out by command. Measurement Specialties HTU21D Digital Humidity Sensor
