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.
