Gravity: HCL Sensor (Calibrated, I2C & UART, 0-10ppm)

The Gravity HCL Sensor is a factory-calibrated electrochemical gas detection module designed for monitoring hydrogen chloride concentrations from 0 to 10ppm. Featuring versatile I2C, UART, and analog outputs, it is ideal for students, makers, and engineers building environmental or industrial sensing projects.

Electrochemical gas detection

This module uses an electrochemical probe specifically engineered to measure hydrogen chloride (HCL) gas. It provides reliable monitoring across a detection range of 0 to 10ppm.

Factory-calibrated accuracy

The sensor comes pre-calibrated from the factory for dependable performance out of the box. This simplifies setup and ensures consistent readings without the need for manual initial calibration.

Multiple communication interfaces

With support for I2C, UART, and analog signal outputs, the sensor easily interfaces with a broad range of microcontrollers. This flexibility allows seamless integration into diverse data-logging architectures.

Industrial and environmental monitoring

Engineered for hazardous gas tracking, this unit is well-suited for industrial safety setups and environmental monitoring systems. It enables makers and engineers to implement continuous air quality surveillance.
