MQ-131 Ozone Gas Detector Sensor Module

The sensitive material of the MQ-131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensors conductivity is higher along with the gas concentration rising. Please use a simple electro circuit, Convert the change of conductivity to correspond output signal of gas concentration. MQ-131 gas sensor has a high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc.

Features:

• Fast response characteristics
• Mounting holes to facilitate fixed installation
• The probe can plug design for easy testing.
• Signal light indicates the output
• Dual signal output (analog output, and TTL-level output)
• TTL output valid signal is low; (low output signal light, can be accessed by the microcontroller IO port)
• Analog output increases with the concentration, the higher the voltage the higher the concentration
• The ozone gas with high sensitivity (detection concentration range 10PPB-2PPM Ozone)
• Long life and reliable stability

Package Includes:

1 x MQ-131 Ozone Gas Detector Sensor Module
