DFRobot Gravity O3 Sensor (Calibrated) - I2C & UART Output
The DFRobot Gravity O3 Sensor is a factory-calibrated electrochemical module for detecting ozone (O3) concentrations from 0 to 10 ppm. It features selectable I2C, UART, and analog voltage outputs for seamless integration with Arduino, ESP32, Raspberry Pi, and other 3.3V/5V logic systems.
Features
- Electrochemical O3 sensor with 0-10 ppm detection range.
- Triple output: I2C, UART (0-3V), and analog voltage for flexible interfacing.
- Factory calibrated with integrated temperature compensation for stable, accurate readings.
- Low power operation (<5 mA) and a long operational life exceeding 2 years in air.
- Gravity interface and provided sample code enable rapid prototyping.

This ozone sensor employs an electrochemical sensing principle, offering high sensitivity and selectivity for ozone gas while providing strong resistance to cross-interference from other common gases. The onboard signal conditioning circuit delivers stable, pre-processed data via your choice of digital (I2C/UART) or analog interfaces.
Designed for durability, the module operates across an industrial temperature range of -20°C to +60°C. Its 32 configurable I2C addresses allow for multi-sensor networks, and the built-in threshold alarm function supports automated system responses. The sensor is part of DFRobot’s comprehensive Gravity gas sensor series, sharing a common form factor and communication protocol for easy system expansion.
