MQ-131 Ozone Gas Sensor Module
The MQ-131 Ozone Gas Sensor Module is the key component of our compact board. Boasting high sensitivity and a rapid response time, this sensor excels at detecting ozone levels (10?1000ppb) in the surrounding air. It utilizes tin dioxide (SnO2) as its sensitive material, which has low conductivity under clean air conditions but increases when exposed to ozone.
MQ-131 Ozone Gas Sensor Module is equipped with a trimmer for adjusting the threshold value, as well as analogue and digital outputs (TTL). Additionally, there is a status LED for monitoring power supply and output signal.
The digital output can be linked directly to a microcontroller, while the analogue output offers a voltage range of 0-5 VDC that corresponds to higher levels of ozone in the surrounding atmosphere.
This power supply operates at a voltage of 5VDC and has dimensions of 31.85×19.65×33 mm. It is compatible with both Arduino and other microcontrollers.
- Both digital and analog output are available.
- The analog output (0-5 VDC) reflects the ozone concentration in the air, with a higher voltage indicating a higher concentration.
- The digital output, with a TTL range of 0-5 VDC, can be utilized to obtain a threshold value. This value can be adjusted using a trimmer and controlled by a microcontroller.
- Blessed with both longevity and unwavering consistency.
- Rapid responsiveness
- Featuring pre-drilled holes for easy installation
- The probe allows for effortless testing with its plug design.
- MQ-131 Ozone Gas Sensor Module can be utilized to develop ozone-detecting devices for both residential and atmospheric settings.
