Gas sensors, also known as gas detectors, are essential electronic devices that identify and detect various gases. They are particularly used to detect toxic or explosive gases and measure gas concentration. Our selection encompasses a wide range of gas sensors, including the following types:
1.Thermopile Gas Sensor: The thermopile gas sensor is one of the earliest developed gas sensors. It can detect various gases such as carbon dioxide, methane, and oxygen. The sensor consists of a thermopile probe and a circuit board. The thermopile probe detects the gas concentration, and the circuit board transmits these signals to the display for users to view the detection results.
2. Optical Gas Sensor: The optical gas sensor is one of the newest gas sensors. It is also capable of detecting various gases such as carbon dioxide, methane, and oxygen. The optical sensor comprises an optical probe and a circuit board. The optical probe detects the concentration of gas, transmitting signals to the circuit board for users to view the detection results.
3.Electrochemical Gas Sensor: This common type of gas sensor can detect various gases such as carbon dioxide, methane, and oxygen. It consists of an electrochemical probe and a circuit board. The electrochemical probe detects the gas concentration, and the circuit board transmits these signals to the display for users to examine the detection results.
4.Metal Gas Sensor: Another common type of gas sensor, it can detect various gases such as carbon dioxide, methane, and oxygen. The metal sensor comprises a metal probe and a circuit board. The metal probe detects the gas concentration, and the circuit board transmits these signals to the display for users to view the detection results.
5.Infrared Gas Sensor: A new type of gas sensor capable of detecting various gases such as carbon dioxide, methane, and oxygen. It consists of an infrared probe and a circuit board; the infrared probe detects the gas concentration, and the circuit board transmits these signals to the display for users to view the detection results.
These sensors are sourced from reputable brands like Winsen, Mikroe, Amphenol, DF Robot, TE Connectivity, Waveshare, Seeed Studio, Adafruit, and Figaro. They find applications in prototyping projects and industrial machines, offering reliability and safety.
