Hot Sale 0-10ppm Smart Gas Detection o3 Ozone Sensor Module
Description
GMQ series ozone sensor module is a general-purpose gas module that combines the electrochemical detection technology developed by our company and the sophisticated circuit design. The use of electrochemical principles to detect the concentration of ozone gas in the air has the characteristics of high sensitivity, high resolution, low power consumption and long service life. Built-in temperature sensor for temperature compensation. UART interface output can be provided to facilitate the back-end reading data.
Features:
1. High sensitivity
2. High resolution
3. Good stability
4. Long service life
5. Strong anti-interference ability
6. Temperature compensation
7. Low power consumption
Application
Disinfection cabinets
Portable instruments
Air quality monitoring equipment
Smart home equipment and other places.
