WEEK 5
Activity: PIR Motion Sensor (Experiment 2)
Assalamualaikum...
As shown as today, is the week fifth i'm gonna try to explain some experiment about the PIR Motion Sensor (HC-SR501).
All experiment that I do were related with my Final Year Project which is DEVELOPMENT OF HOME AUTOMATION SYSTEM USING ANDROID WITH MOBILE APPLICATION.
WHAT IS A PIR MOTION SENSOR
A PIR sensor is one that detect movement in a limited range and normally around 7 feet for the cheaper sensor like I used for this project HAHAHAHA. This sensor sense movement by detecting patches of infrared radiation in front of it.
PIR sensor are more complicated than many of the other sensors because there are multiple variables that affect the sensors input and output. The IR sensor itself is housed in a hermetically sealed metal can to improve noise, temperature, humidity immunity. There are small, inexpensive, low-power, easy to use and don't wear out.
There is a body made of IR-trans-massive material (typically coated silicon since that is very easy to come by) that protects the sensing element. Behind the body are the two balanced sensors. This small thing are normally referred to as PIR "Passive Infrared" or "IR Motion" sensor.

HOW IT WORK..
When a warm body like human or animal passes by, meaning that for the animal not for the small one okay... it first intercepts one half of the sensor, then it will causes a positive differential change between the two halves. The reverse happens when the warm body leaves the sensing area whereby the sensor generates a negative diff. change.So...this is what will happen on the PIR sensor....
For now..already know the basic knowledge of these kinds of sensor...
