Detailed Product Description
Smart Home RF series _ PIR Sensor
-
PIR is short for Passive _Infrared, and the term passive in this instance refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. They work entirely by detecting the energy given off by other objects. PIR sensors don't detect or measure "heat"; instead they detect the infrared radiation emitted or reflected from an object.
-
All objects with a temperature above absolute zero emit heat energy in the form of radiation. Usually this radiation isn't visible to the human eye because it radiates at infrared wavelengths, but it can be detected by electronic PIR devices designed for such a purpose.
-
PIRS-RF03 exactly uses the principal of passive infrared and also merges IOT concept together, so when a human or any other object with heat comes closer within 3 meters from your house, the radiated infrared wave will be detected by PIRS-RF03 immediately, and almost at the same time, it will encode the status and transmit an alert to Gateway and APP on your mobile phone by 2,4GHZ wireless transmission to approach a very cost effective and useful home security system.
-
PIRS-RF03 is powered by 3 pcs of AAA batteries(4.5V 600mAh), the batteries can work continuously for more than 9 months based on max. 20 events detected per day. Mobile phone will push an alert while battery low. Totally 8 pcs of PIRS-RF03 can be installed at the same house.
