MQ-2 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is necessary. Gas sensor is an indoor module and is used at room temperature. The MQ-2 sensor is suitable for the detection of butane, methane, alcoholic, LPG and smoke. It is also sensitive to ignition and combustion of gases. Note Afte...

MQ-7 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. Gas sensor is an indoor module and is used at room temperature. The MQ-7 sensor has high sensitivity to Carbon Monoxide and is able to detect the concentration of carbon monoxide in the air. The measurable concentration range of this s...

MQ-5 Smoke Gas Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kinds of gas combinations. This MQ-5 gas detector is used for leak detection of LPG  (Liquified Petroleum Gas), natural gas and city gas. It has low sensitivity to alcohol and smoke. Note After turning on the module, wait 2 minutes for the internal heater to warmp up. You can download the datasheet of this module here.[wpdm_...

MQ-4 Smoke Gas Module Features MQ series sensors use a small heater inside with an electrochemical sensor in order to measure different kinds of gases combination. This is a simple-to-use compressed natural gas (CNG) sensor, suitable for sensing natural gas (composed of mostly Methane [CH4]) concentrations in the air. MQ-4 has a high switching speed, no noise when switching, and also has a long life. It has a low sensitivity to alcohol and smoke. The sensor normally has a zero output, and its output inc...

MQ-135 Smoke Gas Sensor Module Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure different kinds of gas combinations. The MQ-135 sensor is a sensor for detecting air quality. This sensor is able to detect smoke, CO2, ammonia, alcohol and benzene in the air. Note After turning on the module, wait for 2 minutes until the inside heater warms up. You can download the datasheet of this module here.[wpdm_package id=...
