HTU21D Temperature and Humidity Sensor Module

The main chip on the board is the HTU21D. The HTU21D is a low-cost, easy-to-use, and highly accurate digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging, and is perfect for applications such as weather stations or humidity control systems. With just two lines for I2C communication, you can obtain relative humidity readings and highly accurate temperature measurements.

To start using this sensor in a project, only four pins need to be connected: one for VCC, one for GND, and two data lines for I2C communication. The board includes built-in 4.7k pull-up resistors for I2C communication.
