RD-623 Pyroelectric Infrared Sensor
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.
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
