Overview
Pyroelectric Infrared Sensor detects the infrared radiation by using the temperature-dependent feature.
It suppresses the interference caused by temperature change, adopts the method of dual sensing elements complementary which improves the stability of the sensor.
This PIR sensor can be widely used in safety device, burglar alarm, automatic door, auto light control and intelligent toys.
Key Features
- High sensitivity and excellent signal to noise ratio
- Excellent resistance to EMI interference
- Adopting dual-sensing elements compensation structure, high resistance to external environment interference
- Strong white light resistance
- Components and amplifiers are packaged in TO-5, which saves users time in designing and mounting
Applications
- Security, intrusion alarm, and access control rooms;
- Automatic light switch, safety door;
- Smart building, smart home Appliance;
