The 38th Research Institute of China Electronics Technology Group Corporation (CETC), a key national R&D institution, unveiled its dual-band PIR sensor CETC-PIR-D200 on November 3, which has been officially applied in the State Grid’s smart substation transformation project. The first batch of 80,000 units has been delivered to 200 substations in North China, used for security monitoring of high-voltage equipment areas.
The CETC-PIR-D200 integrates 8-14μm mid-infrared and 14-20μm far-infrared detection bands, enabling simultaneous monitoring of human intrusion and equipment overheating. It has a detection distance of up to 15 meters and a horizontal viewing angle of 120°, supporting wireless communication via LoRaWAN protocol. The sensor is equipped with a built-in self-diagnosis module that can automatically detect hardware failures and send alarm signals to the State Grid’s central monitoring platform. “Smart grid is a key application scenario for industrial sensing,” said Wu Gang, Chief Engineer of CETC 38th Institute. “Our dual-band technology solves the problem of single-function sensors in traditional substations. We plan to supply 300,000 units to State Grid and South Grid in 2026, covering 50% of the domestic smart substation PIR sensor market.”
