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-8 Hydrogen Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combinations. They can be calibrated, but, in order to do that, a known concentration of measured gas or gases is needed. The MQ-8 hydrogen gas sensor is suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm. This sensor has a high sensitivity and fast response time.  Note ...

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-3 Alcohol Gas Sensor Features MQ series sensor uses a small heater inside with an electrochemical sensor in order to measure a different kind of gases combination. The MQ-3 sensor is one of the MQ series heater-driven gas sensors that has an internal variable resistance from pin A to pin B, which depends on the amount of alcohol in the air. The sensor's output is an analog resistance. This sensor can measure the alcohol concentration in human blood alcohol gas on your breath. Alcohol decreases the i...
