Digital Temperature And Humidity Sensor

HTU21D sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the module humidity and temperature digital outputs. HTU21D sensors are low power consumption 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 a which can be read out by command.

Furthermore, the resolution of HTU21D sensor can be changed by command (8/12bit up to 12/14bit for RH/T), low battery can be detected and a checksum improves communication reliability.
With made improvements and the miniaturization of the sensor the performance-to-price ratio has beenimproved a and eventually, any device should benefit from the cutting edge energy saving operation mode.
