Free shipping starting at 50.–
The HTU21D is an affordable and accurate digital humidity and temperature sensor. Thanks to the I2C interface, you can easily read the humidity and temperature. This sensor is perfect for a weather station or any other applications where you want to measure humidity.
Important Info: Activating the I2C pull-up resistors: There are two 4.7 kOhm resistors on the breakout board that pull up the SDA and SCL lines. If you want to operate multiple sensors on I2C, only one breakout board should have the resistors. On the HTU21D breakout board, the resistors are not connected to VCC by default. To activate them, you need to connect the three solder points on the top of the board with solder.
