The Gravity: Electrochemical Ozone Sensor is a high-precision sensor designed to measure ambient ozone (O₃) concentrations from 0 to 10 ppm, making it ideal for air quality monitoring, smart homes, disinfection equipment, and environmental research. Built on electrochemical sensing principles, it offers high sensitivity, excellent stability, and anti-interference capability.
This compact sensor supports I2C digital output and features a Gravity 4-pin interface, making it fully compatible with Arduino, ESP32, Raspberry Pi, and micro:bit. It provides a resolution of 0.01 ppm (10 ppb) and operates on a wide voltage range (3.3V–5.5V). Designed for ease of use, it comes with ready-to-use libraries and sample code for rapid integration into your IoT or air quality system.
