O3 gas sensor

Product catalog summary

Product Description
The RK03Y electrochemical ozone module is a compact, versatile device designed for detecting ozone (O3) in the air using electrochemical principles. It offers high selectivity and stability, with built-in temperature compensation and both digital and analog output modes.

Module Features

High sensitivity and resolution
Low power consumption
Long service life
UART data output
High stability and anti-interference
Temperature compensation and linear output

Main Applications

Portable meters
Disinfection cabinets
Air quality monitoring equipment
Air purifiers
Fresh air ventilation systems
Smart home equipment

Technical Index
The module operates with a voltage input of 3.7V to 5.5V and communicates via UART with a baud rate of 9600. It supports both active uploading and question-answering communication modes.

Communication Protocol

Active uploading sends concentration values every second.
Switching between modes requires specific command formats.
Gas concentration is calculated using high and low concentration bytes.

Cross-Interference Characteristics
The module exhibits excellent anti-interference performance, with minimal response to gases other than ozone. A table of typical responses to various gases is provided.

Precautions

Quick soldering is required to avoid sensor damage.
Aging time before use should be at least 48 hours.
Avoid contact with organic solvents, paints, and high-concentration gases.
Do not encapsulate with resin materials or expose to oxygen-free environments.
Ensure a clean atmosphere for zero-point measurement.
Avoid blocking or polluting the sensor's intake surface.
Do not open the waterproof membrane or cause physical damage.
Store with electrodes in a short circuit state.
Avoid long-term exposure to high-concentration alkaline gases.
