Compared with traditional principle gas sensors, gas sensors based on the infrared absorption principle have advantages such as good stability, strong selectivity, no dependence on oxygen, wide detection range, long lifespan, long maintenance cycle, and strong anti-interference ability. They are the trend in gas detection development and can quickly replace sensors based on traditional principles. 

The XSIR-4CH4-100 infrared methane sensor is designed using the latest technology, adopting a low-power processor and infrared light source to control overall power consumption while ensuring stable operating current of the sensor. The sensor uses newly designed algorithms, including gas concentration algorithms, calibration algorithms, and temperature compensation algorithms. It is equipped with a 32-bit core industrial-grade microprocessor, which has fast computing speed and a wide operating temperature range. Combined with the latest algorithms, it ensures high efficiency, high accuracy, stable and reliable data computation, and adaptability to different working environments.
