DFRobot Gravity HCL hydrogen chloride sensor I2C and UART

The Gravity HCL Hydrochloric Acid Sensor from DFRobot is a precise, factory-calibrated sensor specifically designed for measuring 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 ensures high accuracy, stability, and excellent resistance to interference. An integrated temperature compensation and a threshold alarm function 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.

Features:

• High precision and sensitivity in HCL detection.
• Supports analog, I2C, and UART output modes.
• Durability with a lifespan of over two years.
