Product Description

The DFRobot Gravity: HF Sensor (Calibrated) - I2C & UART is an electrochemical gas sensor module for measuring hydrogen fluoride concentration in ambient environments. It combines a factory-calibrated HF probe with a signal conversion board and provides three output modes: analog, I2C, and UART. This allows integration into a wide range of monitoring and control systems.

The probe uses the electrochemical sensing principle and is intended for stable, sensitive HF detection. According to the manufacturer, the module provides an integrated temperature compensation algorithm, a threshold alarm function, and 32 modifiable I2C addresses. It is compatible with common development and embedded platforms such as Arduino, ESP32, and Raspberry Pi, making it suitable for building hydrogen fluoride detection systems in industrial and environmental applications.
