## Description

The Gravity IIC Ozone Sensor measures ozone (O₃) concentration from 0 to 10 ppm with 10 ppb resolution using an electrochemical sensing element. Factory-calibrated for accurate readings out of the box, it connects via I2C through DFRobot's Gravity 4-pin interface. Compatible with Arduino, ESP32, Raspberry Pi, and other 3.3–5.5V microcontrollers, this sensor is suited for air quality monitoring, disinfection equipment, and environmental sensing applications. The electrochemical cell has a working life of over 2 years in air. Key Features Electrochemical Ozone Sensing – Factory-calibrated for accurate O₃ measurement 0–10 ppm Range – With 10 ppb (0.01 ppm) resolution I2C Output – Simple digital interface via Gravity 4-pin connector Wide Voltage Input – 3.3–5.5V DC compatible 2+ Year Lifespan – Electrochemical cell rated for over 2 years in air Specifications Detection Gas – Ozone (O₃) Measuring Range – 0–10 ppm Resolution – 0.01 ppm (10 ppb) Operating Voltage – 3.3–5.5V DC Interface – I2C (Gravity 4-pin) Warm-Up Time – ≤3 minutes Response Time – ≤90 seconds Recovery Time – ≤90 seconds Operating Temperature – −20 to 50°C Operating Humidity – 15–95% RH (non-condensing) Dimensions – 37 × 27 mm Ideal For Air quality monitoring stations Disinfection equipment monitoring Smart home environmental sensing Portable ozone detection instruments Warning: The sensor requires a 24–48 hour initial warm-up on first power-up. Do not open the white waterproof membrane, expose to corrosive gases, organic solvents, or strong air convection. Avoid excessive shock or vibration.
