MQ131 Fuel Sensor Module
Sensitive material of MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electro circuit, Convert change of conductivity to correspond output signal of gas concentration. MQ131 gas sensor has high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc.
Features: MQ131 Gas Sensor
- With the signal light indicates the output
- The 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)
- The 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)
- With a long life and reliable stability
- Fast response characteristics
- With mounting holes to facilitate fixed installation
- The probe can plug design for easy testing.

Description
MQ131 Fuel Sensor Module is supposed to allow LPG detection interface to Microcontroller with out ADC Channels. It permits to work out when a preset LPG fuel degree has been reached or exceeded. Interfacing with the sensor module is accomplished by a 4-pin SIP header and requires One I/O pin from the host microcontroller.
The onboard microcontroller present preliminary heating interval after powerup then begins to meassure LPG sensor output.If it discovered the LPG contents above setted worth, it’s going to inform the Host controller by pulling the Output Pin to Excessive and Begins to blink aonboard standing LED. The sensor module is very meant to provide a method of evaluating LPG sources and being able to line an alarm restrict when the supply turns into extreme.
A primary fuel sensor module has 6 terminals throughout which 4 terminals (A, A, B, B) acts enter or output and subsequently the remaining 2 terminals (H, H) are for heating the coil. of these 4 terminals, 2 terminals from all sides are sometimes used as both enter or output.
These modules comprises the fuel sensor and a comparator IC. Now let’s see the pin description of the fuel sensor module which we’ll typically use with an Arduino. The fuel sensor module principally consists of 4 terminals:Vcc – Energy provide and GND – Energy provide. Digital output – This pin provides an output both in logical excessive or logical low (0 or 1) which means it shows the presence of any poisonous or flamable gases close to the sensor.
Analog output – This pin provides an output steady in voltage which varies supported the focus of fuel that is utilized to the fuel sensor.
Delicate materials of MQ131 fuel sensor is O3 SnO2, which with decrease conductivity in clear air. When Ozone fuel exists. The sensor’s conductivity is extra greater alongside aspect the fuel focus rising. Please use easy electro circuit, Convert change of conductivity to correspond output of fuel focus. MQ131 fuel sensor has excessive sensitivity to Ozone, additionally delicate to O3 CL2, NO2, and many others.
