Overview of pir sensor d204b
D204B come standard with enhanced immunity to EMI (Electro-Magnetic Interference). It widely used in security system.
Senba PIR sensor can detect the wavelengths humans emit which is 8-10um, but Senba PIR can detect 7- 14um. It can be used in security and automation applications. For security applicance, PIR sensor are integrated into the alarm system. There are ceiling type and wall hanging type. For automation applications, PIR sensor can be integrated into the light control system, automatically turn on the light when somebody enter the detect rang, automatically turn off the light when sombody exit the detect range.
Low Current Consumption
Simplified Circuitry with Fully Integrated Sensor
The PIR motion sensor adopts high-performance infrared detector. As long as human cross through its detection range, the infrared switch generates an electrical signals.
