MQ-131 Ozone Gas Detection Sensor Module

MQ-131 Ozone Gas Detection Sensor Module is a semiconductor gas sensor module designed to detect ozone (O₃) concentration in the air. It uses a tin dioxide (SnO₂) sensing element whose conductivity changes in the presence of ozone, allowing the module to detect changes in ozone concentration. The module provides an analog output and an adjustable digital output, making it suitable for Arduino, Raspberry Pi, air-quality monitoring, ozone generator monitoring, environmental sensing, and DIY gas-detection projects.

Features:

1. Designed for ozone (O₃) gas detection.
2. Uses a tin dioxide (SnO₂) semiconductor sensing element.
3. High sensitivity to ozone gas.
4. Available in low-concentration and high-concentration MQ-131 variants.
5. Analog output for monitoring ozone concentration.
6. Digital output with adjustable detection threshold.
7. Onboard potentiometer for digital output sensitivity adjustment.
8. 5V DC operating voltage for typical module configurations.
9. Fast response to changes in ozone concentration.
10. Requires sensor preheating for stable measurements.
11. Suitable for Arduino, Raspberry Pi, ESP32, and other microcontroller projects.
12. Useful for air-quality and environmental monitoring.
13. Suitable for monitoring ozone generators and ozone-producing equipment.
14. Compact PCB module design.
15. Suitable for DIY, laboratory, and educational gas-sensing applications.
