Intelligent Gas Sensor

Freon sensor, a magical device that combines high technology and practicality. Its construction is extremely sophisticated, mainly consisting of two major components: the sensing element and the signal processing circuit. The sensing element is like a super detective, possessing ultra-high sensitivity and accuracy. Once Freon gas comes into contact with the sensing element, its resistance value immediately changes. This change is like a mysterious signal, indicating the presence and concentration of Freon gas. The signal processing circuit, on the other hand, acts as a clever assistant, processing and analyzing this signal, accurately converting the change in resistance value into an easily understandable Freon gas concentration value. In this way, we can use the Freon sensor to monitor the concentration of Freon gas in real-time, ensuring environmental safety. Moreover, Freon sensors are widely used in various fields such as refrigeration and firefighting, significantly improving work efficiency and safety.
