Gas Sensor(MQ2) module is useful for gas leakage detecting(in home and industry). It can detect LPG, i-butane, methane, alcohol, Hydrogen, somke and so on. Based on its fast response time. measurements can be taken as soon as possible. Also the sensitivity can be adjusted by the potentiometer.
MQ-2 Semiconductor Sensor for Combustible Gas:
Description: This Alcohol Sensor MQ3 is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-3.3V ADC.
Methane CNG Gas Sensor MQ4 is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. The MQ-4 can detect natural gas concentrations anywhere from 200 to 10000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.
LPG Gas Sensor (MQ6) Features:
MQ-7 is a Carbon Monoxide (CO) sensor, suitable for sensing Carbon Monoxide concentrations(PPM) in the air. The MQ-7 sensor can meassure CO concentrations ranging from 20 to 2000ppm. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple , just a voltage devider; all you need to do is power the heater coil with 5V DC or AC , add a load resistance, and connect the output to an ADC or a simple OPAMP comparator.
We are instrumental in presenting qualitative LPG & Natural GAS Sensor MQ5 which ensures optimum safety and security in the industries and domestic sector. These easy to install are highly suitable for detecting the presence of natural gas, LPG, fumes, smoke and town gas. The sensor in this system is highly reliable and is provided with a simple drive circuit for facilitating easy operations.
The analog gas sensor - MQ2 is used in gas leakage detecting equipments in consumer and industry markets, this sensor is suitable for detecting LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke.It has a high sensitivity and fast response time.And the sensitivity can be adjusted by the potentiometer.
Sensitive material of MQ-5 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensors conductivity is more higher along with the gas concentration rising. The sensor convert change of conductivity to correspond output signal of gas concentration.
MQ-5 gas sensor has high sensitity to Methane, Propane and Butane, natural gas and could be used to detect both Methane and Propane.
