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
- High temperature-dependent stability
- Strong anti-jamming ability (e.g. vibration, radio-frequency interference etc.)
- High value with competitive price
Applications
- Safety Alarm
- Electricity Lighting
- House-hold and other smart home fields
