The HTU21D digital relative humidity sensor is packaged in a reflow-friendly dual flat no-lead (DFN) package, measuring 3 x 3mm and 1mm high, and provides a digitally calibrated, linearized signal in I2C format. The HTU21D sensor is a dedicated temperature and humidity plug-and-play sensor for OEM applications that require reliable and accurate measurements. Direct interface to microcontrollers via modular temperature and humidity digital outputs.

The HTU21D's small size and low power consumption are designed for applications where equipment space is small and product is sensitive. Every sensor is calibrated and tested. The product batch number is printed on the surface of the product, while the electronic identification code is stored in the chip - which can be read by entering a command.

In addition, the resolution of the HTU21D sensor can be changed by inputting commands (8/12-bit or even 12/14-bit RH/T), the sensor can detect the low battery state and output a checksum, which helps to improve the communication efficiency. reliability. Thanks to improved and miniaturized sensors, it is more cost-effective - and ultimately all devices will benefit from cutting-edge energy-efficient operating modes. <
