Gravity: Factory Calibrated Electrochemical CO Sensor (0-1000 ppm, I2C & UART)

The Gravity Factory Calibrated Electrochemical CO Sensor is a precision carbon monoxide detector capable of measuring concentrations from 0 to 1000 ppm. Equipped with factory calibration, built-in temperature compensation, and multiple output options, it suits students, makers, and engineers developing industrial safety or environmental monitoring projects.

Factory-calibrated electrochemical probe

Using electrochemical sensing principles, this pre-calibrated probe delivers high sensitivity, strong anti-interference performance, and a lifespan exceeding two years in ambient air. It provides immediate and dependable measurement of carbon monoxide without requiring manual calibration.

Triple output modes and I2C addressing

The module supports I2C, UART (0 to 3V), and analogue voltage outputs for broad design flexibility. It features 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and an onboard threshold alarm function.

Standardised gas sensor ecosystem

This module is part of a 12-sensor gas detection range sharing identical operational methods and data formats. This allows straightforward expansion and cascading when monitoring multiple target gases in a single system.

Low-power microcontroller compatibility

Operating between 3.3V and 5.5V DC at less than 5mA, the 37 x 32 mm conversion board pairs easily with Arduino, ESP32, and Raspberry Pi. The included 4-pin Gravity cable enables quick, plug-and-play wiring.

Versatile environmental applications

Rated for operating temperatures from -20°C to 50°C and humidity up to 90% RH, the sensor performs reliably in poorly ventilated spaces. It is well suited for portable safety devices, warehouse air monitoring, mining, and petrochemical installations.
