DFRobot Gravity HF hydrogen fluoride sensor I2C and UART

The Gravity HF Hydrogen Fluoride Sensor from DFRobot is an advanced, factory-calibrated sensor designed for the precise measurement of hydrogen fluoride (HF) in the air. With a measurement range of 0 to 10 ppm and support for analog, I2C, and UART output modes, this sensor provides a comprehensive solution for a variety of applications, from industrial monitoring to environmental protection projects. The electrochemical measurement method ensures high accuracy, stability, and excellent resistance to interference. An integrated temperature compensation feature and an alarm function for threshold values further enhance the sensor's reliability. Thanks to its compatibility with common microcontrollers such as Arduino, ESP32, and Raspberry Pi, the sensor can be easily integrated into existing systems.
