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.

The HTU21D is a low-cost, easy to use, highly accurate, digital
humidity and temperature sensor. This sensor is ideal for environmental
sensing and data logging and perfect for a weather stations or humidor
control systems. All you need is two lines for I2C communication and
you’ll have relative humidity readings and very accurate temperature readings as a bonus!
There are only four pins that need to be hooked up in order to start
using this sensor in a project. One for VCC, one for GND, and two data
lines for I2C communication. This breakout board has built in 4.7k pull up resistors for I2C communications.
