Gravity HCL Hydrochloric Acid Sensor I2C and UART

The Gravity HCL Hydrochloric Acid Sensor by DFRobot is a precise, factory-calibrated sensor, specifically designed for the measurement of hydrochloric acid concentrations in the air. With a measurement range of 0 to 10 ppm and the ability to communicate via analog, I2C, and UART output modes, this sensor offers a flexible solution for industrial monitoring, environmental protection projects, and more. The electrochemical measurement method guarantees high accuracy, stability, and excellent resistance against disturbances. An integrated temperature compensation and threshold alarm function further enhance the reliability of the sensor. Thanks to its compatibility with popular microcontrollers such as Arduino, ESP32, and Raspberry Pi, the sensor can be easily integrated into existing systems.

Features:

• High precision and sensitivity in HCL detection.
