Description: Air quality sensor for detecting a widerange of gases, including NH3, NOx, alcohol, benzene, smoke andCO2. Ideal for use in office or factory. MQ135 gas sensorhas high sensitivity to Ammonia, Sulfide and Benze steam, alsosensitive to smoke and other harmful gases..
Thereof, how does mq135 sensor work?
An alcohol sensor detects the attentiveness ofalcohol gas in the air and an analog voltage is an output reading.The sensor can activate at temperatures ranging from -10 to50° C with a power supply is less than 150 Ma to 5V. Thesensing range is from 0.04 mg/L to 4 mg/L, which is suitablefor breathalyzers.
One may also ask, what is MQ in MQ sensor? MQ sensors are special sensors designed tohave sensitivity for to detect some gas like LPG, CO, Propane etc.In Chinese, 'sensitive' means 'Mĭngăn' and 'Gas to' means'Qǐ lai'. So I think, more or less, MQ stands for thesensors having sensitivity towards (or to) gas.
Subsequently, question is, how does an alcohol sensor work?
The maximum level of alcohol that may beaccurately detected by evidential breath testers is 220 μg/100ml air. They work on the principle that in the presence of acatalyst, oxygen in a sample of expired air converts anyalcohol present into acetic acid and then to water andcarbon
How does a gas sensor work?
A gas sensor is a device which detects thepresence or concentration of gases in the atmosphere. Basedon the concentration of the gas the sensor produces acorresponding potential difference by changing the resistance ofthe material inside the sensor, which can be measured asoutput voltage.
