Gas Sensors

Product Details:

 

MG-811 Carbon Dioxide Sensor Module for detecting Metal Oxide Sensor Carbon Dioxide (CO2), which needs to heat the tank to the specified level. With power supply This creates heat vapor and separates the CO2 from the air in general.

This sensor module has an MG-811 on-board as the sensor component. There is an on-board signal conditioning circuit for amplifying output signal and an on-board heating circuit for heating the sensor. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. It could be used in air quality control, ferment process, in-door air monitoring application. The output voltage of the module falls as the concentration of the CO2 increases.

 

Additional Information:

• Item Code: MG811

Product Details:

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.

Features:

• Support both the output digital value and the output analog value.
• High sensitivity to Combustible gas in wide range .
• Can detect liquefied gasMethane,Butane, Propane and natural gas .
• Adjustable Sensitivity , Stable Performance.
• Pin Connection: GND: Ground, Dout: digital output, Aout: analog output Vcc: 5V
• Applicable to a variety of platforms including Arduino / AVR / ARM.

Product Details:

MQ3 GAS Sensor is a very easy to use and very handy sensor. It is suitable for sensing Alcohol gas concentration. MQ3 Alcohol GAS Sensor can detect Alcohol gas concentrations anywhere from 200 to 10000 ppm. The MQ3 GAS sensor has a very hight sensitivity to Alcohol gas. The sensitive material of MQ3 Sensor is SnO2, which has lower conductivity in clean air. When the target alcohol gas exist, the sensor’s conductivity is higher along with the gas concentration rising. MQ3 GAS sensor has high sensitivity to Alcohol, and good resistance to disturb of gasoline, smoke and vapour. The sensor could be used to detect alcohol with different concentration, it is with low cost and suitable for different application.

Features of MQ3 Alcohol GAS Sensor:

• High sensitivity to Alcohol Rs (in air) Rs (0.4mg/l alcohol).
• Heater voltage = 5.0V

Application of MQ3 Alcohol GAS Sensor:

• Drunk Driver detection system
• Portable alcohol detector
