GRS-RHSI is an Multi-function detecting sensor which integrates Temperature/Humidity, Smoke and PIR.。It adopts advanced temperature and humidity sensing chip to monitor using environment. Adopts smoke module which is design with integrated chips, use for smoke monitoring and alarm. Adopts imported passive infrared sensor and microwave module, effectively detect movement of the people, and also alarm according to the need. The Multi-function detecting Sensor can be used in the palce of needing to detect the temperature humidity smoke and people , including the building , marketplace, the data center, base station and so on. It can effectively reduce the complexity of the installation, operation and maintenace. Its outstanding performance to make it having a very high cost performance.
