Compared with traditional principle gas sensors, gas sensors based on the principle of infrared absorption 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 development trend in gas detection and can quickly replace traditional principle gas sensors. 

The XSIR-4C3H8-100 infrared propane gas sensor is designed using the latest technology, employing a low-power processor and infrared light source, controlling the overall power consumption while stabilizing the sensor's operating current. The sensor uses the latest designed algorithms, including gas concentration algorithms, calibration algorithms, and temperature compensation algorithms. The sensor adopts a 32-bit core industrial-grade microprocessor, which has fast computing speed and a wide operating temperature range. Together with the latest algorithms, it ensures high efficiency, high accuracy, stability, and reliability of sensor data calculation, and adapts to different working environments.
