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 transmittance and good selectivity filter
- Adopting dual-sensing elements compensation structure, high resistance to external environment interference
- High sensitivity and excellent signal to noise ratio
- High Stability and strong anti-jamming ability (e.g. vibration, radio-frequency interference etc.)
Applications
- Security, Intrusion alarm;
- Indoor access management;
- Human detection lighting;
- Auto control door;
- Smart home, smart office and smart building
