HTU21D Temperature & Humidity Sensor is a premium quality Humidity & Temperature Sensor. You can buy this Sensor from Robu. in at a reasonable price.

The HTU21D Temperature and Humidity Sensor Module 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 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. The measured time of this sensor is up to 50 msec

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. If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors.


Full drops of water can damage the sensor. We recommend wrapping the board in Teflon/irrigation tape for extreme conditions where water droplets may find their way into the sensor.

Note : HW-520 & HW-220 on module doesn’t affect the working of product .

    Good product. Gives accurate temperature and relative humidity readings. This board is similar to SparkFun’s HTU21D breakout board. You can easily hook it up with Arduino read data from it using the SparkFun HTU21D library.
