MQ5 is a LPG Gas Sensor 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, town gas and avoid the noise of alcohol and cooking fumes and cigarette smoke.. The sensor in this system is highly reliable and is provided with a simple drive circuit for facilitating easy operations.
Features of MQ5 LPG Gas Sensor:-
High sensitivity to LPG, natural gas , town gas
Small sensitivity to alcohol, smoke.
Fast response .
Stable and long life
Simple drive circuit
Applications MQ5 LPG Gas Sensor:-
Gas leak detection system
Fire/Safety detection system
Gas leak alarm
Gas Sensor(MQ5) module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible.
Sensitive material of mq-2 gas sensor is sno2, which with lower conductivity in clean air. When the target combustible gas exist, 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. Mq-2 gas sensor has high sensitivity to lpg, propane and hydrogen, also could be used to methane and other combustible steam, it is with low cost and suitable for different application. Wide detecting scope. Stable and long life. Fast response and high sensitivity. Simple drive circuit. The grove - gas sensor(mq2) module is useful for gas leakage detecting(in home and industry). It can detect lpg, i-butane, methane, alcohol, hydrogen, smoke 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. Specifications: Detection range: 300 to 10000 ppmm, characteristics of gas: 1000 ppmm isobutene, sensitivity: R in air/rin typical gas >=5, sensitive resistance: 1k ohm to 20k ohm in 50ppm toluene, ambient temperature: 20? ~ Plus 55?, Measure the voltage<=24v.
High sensitivity to Propane, smoke, Hydrogen, LPG, CO, alcohol, Smoke.
Fast response time <10s
Stable and long life
Connecting five volts across the heating (H) pins keeps the sensor hot enough to function correctly. Connecting five volts at either the A or B pins causes the sensor to emit an analog voltage on the other pins. A resistive load between the output pins and ground sets the sensitivity of the detector.
