Product Description:
Overview
Senba is the specialist PIR manufacturer 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.
HM612 is a newest smart pir human motion sensor. This Smart digital detector offers a complete motion detector solution, with all electronic circuitry built into the detector housing. Only a power supply and power-switching components need to be added to make the entire motion switch, a timer is included. The series has versions which can include ambient light level and sensitivity adjustments.

Applications
Smart Lighting
Infrared automatic PIR sensor light
Using battery power supply, PIR sensors are easily used in entrance, bathroom, corridor, and other temporary lighting places.
Compared to sound-control lights, pyroelectric sensor has better anti-jamming effect. Only sensitive to human body temperature. To light, when person come, and light off when person leave.
Faq
1.Why is long range outdoor pir motion sensor called passive?
The long range pir motion 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?
Most low-cost motion detectors can detect up to distances of at least 15 feet (4.6 m).
