What's the quality of the pyroelectric flame sensor introduced by Saiya Sensing?

The project we are doing recently is to use the Saiya pyroelectric flame sensor. Whether the electric flame sensor is good or not mainly depends on the sensitivity and stability, which involves the core chip of the sensor. As a sensor company that has been able to independently research and develop chip technology for more than 20 years, Saiya has also obtained the patent of MEMS thermopile chip. The market reaction is greatly wrong, and the product quality is undoubtedly reliable. Moreover, his family's explosion-proof certificate, CPA, CMC and other certificates are available, so you can use them with confidence.
