Precision sensor for temperature and humidity, HTU21D, compatible with Arduino and other development boards, which communicates with the microcontroller via I2C. The sensor is compatible with logic voltages up to 3.3V, this means that a logic level converter will be necessary if it is used with development boards that work with a logic voltage of 5V or higher. alternatively, a 10K resistor can be added on the SD and SCL lines when used with 5V development boards.

The board has 4 pins, 2 for power (VCC and GND) and 2 for communication (SDA and SCL). There is a 4.7K "pull up" resistor for I2C communication. When connecting several devices to the same bus, these resistors will have to be deactivated. From the factory, the board comes with the resistors disabled. To activate the resistors, solder the 3 jumpers together on the board.

For use with Arduino, the "HTU21D.h" library will be installed and can be tested using the example code related to this library.
