The GY-21 HTU21 Sensor Module is an affordable and user-friendly digital sensor designed for high-precision humidity and temperature measurements. This module excels in environmental sensing and is perfect for applications like weather stations, greenhouses, and humidor control systems. Its ease of use is highlighted by its simple I2C communication setup, requiring only two lines to transmit data. In addition to providing reliable relative humidity readings, the sensor also delivers highly accurate temperature measurements, making it a versatile addition to any project.
The GY-21 module features just four connection pins: one for VCC, one for GND, and two for I2C data communication. Built-in 4.7k pull-up resistors enhance I2C functionality, ensuring stable communication. If you’re integrating multiple I2C devices on the same bus, you can easily disable these resistors for optimal performance. With its compact design and straightforward setup, the GY-21 HTU21 Sensor Module is an excellent choice for anyone looking to monitor environmental conditions effectively.
