Overview
Senba is one of the most professional PIR sensor manufacturers for more than 15 years. We are the most advanced factory with complete categories. With strong R&D center, there are digital type and analog type, dual elements and four elements for you choose. The market cover domestic market, Korean, Amertica, Turkey and Europe.
PIR Sensor 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.
Features
Low Current Consumption
Simplified Circuitry with Fully Integrated Sensor
Wide angle
Applications
Sensor Switch
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.
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?
PIR D204B can detect up to distances of 8- 10M.
