The MQ-7 carbon monoxide sensor is especially designed to be sensitive to carbon monoxide (CO) gas which is emitted by vehicles, factories, etc.
Structure and configuration of MQ-6 gas sensor is shown as Fig. 1 (Configuration A or B), sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel net. The heater provides necessary work conditions for work of sensitive components. The enveloped MQ-6 have 6 pin ,4 of them are used ...
The MQ7 is a simple-to-use Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect CO-gas concentrations anywhere from 20 to 2000ppm. The sensitivity can be adjusted by the potentiometer.

I had previously published a project with an MQ sensor and received a lot of critical feedback on it. Today I also expect your feedback, but only of a positive nature: with the MQ-7 carbon monoxide gas sensor and the matching PCB from Pololu, analog measurement using the ADC from the Arduino is no longer a problem. I followed the recommendation to use a 10KOhm resistor and soldered the MQ7 to ...
The sensor converts a pressure into an analog output signal. The calibrated transfer function converts a pressure of 40 kPa to 115 kPa into a voltage range of V to V. The chip is packaged in a “green” SMD housing. The sensor has been primarily developed for measuring barometric air pressure, but can also be used in other application fields. The high accuracy and the high ...

Sensors must avoid exposing to silicon bond, fixature, silicon latex, putty or plastic contain silicon environment. High Corrosive gas If the sensors are exposed to high concentration corrosive gas (such as H 2 S, SO X, Cl 2, HCl etc.), it will not only result in corrosion of sensors structure, also it cause sincere sensitivity attenuation. Alkali, Alkali metals salt, halogen pollution ...

Sensitive material of MQ-7 gas sensor is SnO2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO at low temperature(heated by ).The sensor’s conductivity gets higher along with the CO gas concentration rising. At high temperature(heated by ),it cleans the other gases adsorbed at low temperature. Users can …
