Turns on automatically- PIR sensor.
Not like PIR sensor outside the lamp.
Much more effective than previous PIR sensors.
A great page on PIR sensors from GLOLAB\\.
PIR sensors don't detect or measure"heat";
There are two‘timeouts' associated with the PIR sensor.
The pir sensor working distance is 3 meter.
The input is also ideal, for instance,when using a PIR sensor.
PIR sensors are widely used in motion detecting devices.
Much more effective at detecting movement than PIR sensor Tubes.
PIR sensor Angle: 180° Distance: 9-36 feet sensitivity adjustable.
It is with camera, doorbell button, PIR sensor, with multi functions.
At the same it, it support to connect alarm,door contact and pir sensors.
Unfortunately this PIR sensor is mislabeled(it looks like they swapped R9 R17).
Generally, microwave sensors have much better sensibility compared to the PIR sensors.
PIR sensors are rather generic and for the most part vary only in price and sensitivity.
A practical intruder alarm system using PIR sensor and 8051 microcontroller is also included at the end of this article.
A PIR sensor can be connected to a relay(perhaps with a transistor buffer) without a micro!
Microwave sensors can alsoperform well if there is any metalloid barrier, which the PIR sensors cannot.
These stats are for the PIR sensor in the Adafruit shop which is very much like the Parallax one.
For many basic projects or products that need to detect when a person has left orentered the area, PIR sensors are great.
Moreover, the sensibility of PIR sensors is also compromised if the ambient temperature is more than 35?
PIR sensors are rather generic and for the most part vary only in price and sensitivity.
The design patent of Wolf-guard PIR sensor HW-03D(product details plc click here). Patent No. 003870534-0001;
The other type uses PIR sensor to detect the temperature of the moving object to sense motions.
Moreover, the sensibility of PIR sensors is also compromised if the ambient temperature is more than 35ᵒ Celsius.
An easy way of prototyping with PIR sensors is to connect it to a breadboard since the connection port is 0.1″ spacing.
In this Arduino Tutorial we will learn how a PIR Sensor works and how to use it with the Arduino Board for detecting motion.
