DFRobot Gravity HCL Sensor (Calibrated) - I2C & UART

• DFRobot Gravity HCL Sensor (Calibrated) - I2C & UART
• Offers high stability and high sensitivity
• Detects Hydrogen chloride (HCL) gas
• Strong anti-interference ability
• Supports three output modes analog, I2C, and UART
• Working Voltage: 3.3 ~ 5.5 V DC

The DFRobot Gravity HCL Sensor (Calibrated) - I2C & UART detects hydrogen chloride concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of hydrogen chloride in the environment. Can be widely used in the detection of hydrogen chloride in industrial and environmental protection fields.

The probe adopts the electrochemical principle, has the characteristics of strong anti-interference ability, high stability, high sensitivity, etc., and the service life is as long as two years.

The sensor has 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and a threshold alarm function, It has good compatibility with mainstream main control devices such as Arduino, ESP32, and Raspberry Pi. The easy-to-use Gravity interface, coupled with the sample code, can quickly build a Hydrogen chloride concentration detector.

DFRobot has introduced 12 gas detection sensors in this series, CO, O2, NH3, H2S, NO2, HCL, H2, PH3, SO2, O3, CL2, and HF, which are used in exactly the same way and data format, so you can combine them according to your needs.
