Product Description
Overview
D204B come standard with enhanced immunity to EMI (Electro-Magnetic Interference). It widely used in security system.
Senba d204b PIR sensor can detect the wavelengths humans emit which is 8-10um, but Senba PIR d204b 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.

Applications
Sensor Switch
The PIR motion sensor adopts high-performance analog infrared detector. As long as human cross through its detection range, the infrared switch generates an electrical signals.
FAQ
1. Why is PIR sensor called passive?
The sensor is called passive because it doesn't emit light to get measurements. The sensor in PIR is actually split into two parts. The reason for that is to measure motion. ... The sensor is also sensitive enough to even detect IR radiation source movement while the object is already in it's field of view.
2. How far can a motion sensor detect?
D204B can detect up to distances of 8- 10M.
PIR , pyroelectric infrared sensor, is normally known as a motion detector. It is a intelligent pir sensor based on measuring infrared light radiating from objects within its field of view. The detector itself cannot emit infrared. It is commonly used in burglar alarms and smart lighting applications.
Normally PIR works with a fresnel lens. The human body has a constant body temperature, which is different from the ambient temperature. When a human body moves, this difference is detected by PIR through a Fresnel lens, which outputs an signal.
