Gas sensors are instruments used to detect specific gases and vapors. A gas sensor usually has an active element that responds to the gas by producing an electrical signal. This signal can be accurately measured and used to determine the concentration of the gas in the environment. The VQ635M/2 is an electrochemical gas sensor which uses a two-cell design for improved sensitivity. It is widely used for monitoring indoor air quality in buildings, residences, and laboratories.

The VQ635M/2 sensor is designed for the detection of combustible gases in the air. It has a fast response time and can be used with various types of equipment, such as controllers, measuring systems, and alarms. The sensor can detect gases such as methane, propane, and hydrogen. It is also capable of detecting lower levels of these gases than other sensors. The VQ635M/2 is used in a variety of applications such as air quality monitoring, ventilation control, fire and gas detection, and occupational safety monitoring.

The working principle of the VQ635M/2 is based on the electrochemical reaction that occurs between the gas and an electrolyte. The electrolyte is an electrolyte solution that serves to conduct electricity between the active surfaces of the cell. The active surface of the cell is composed of a porous material, such as carbon or graphite, that is coated with a catalyst. The catalyst promotes the electrochemical reaction between the gas and the electrolyte. As the gas reacts, the voltage at the cell surface changes, allowing the level of the gas to be detected.

When using the VQ635M/2, the current is flowed through the two cells of the sensor. The voltage generated at the active surfaces is measured, and the resulting signal is processed by a microcontroller to determine the concentration of the gas. The microcontroller can also be used to set the alarm threshold for the gas. Once the sensor’s threshold is exceeded, an alarm is triggered.

The VQ635M/2 is a versatile sensor that can be used in a variety of applications. The sensor is particularly suited for monitoring indoor air quality, as it is capable of detecting even lower levels of combustible gases. The sensor is also rugged and reliable, and has a long lifespan. The sensor is easy to install and maintain, making it an ideal choice for many applications.
