· Third line: int Pir = 2; Space between int and Pir, and it has to start on a new line, otherwise it's part of the comment. Fourth line: int Relay = 3; (2 = the Pir) Fifth line: int Presence; needs a semicolon. If you have the same Pir sensor as in the picture, set the sensitivity pot in the middle, and the 'time' pot fully anti-clockwise. Start ...
· Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated. How do you trigger a motion detector? A small quantity of warm but not boiling water will often trigger a PIR (safety in mind) or on a cold day just tap water ...

· This PIR sensor’s domed lens is made up of Fresnel lenses, Fresnel lenses were designed to save on weight, space, and material while achieving the same qualities of a larger and denser lens. A normal lens is a solid piece of glass forming a continuous convex arc. That glass can be heavy and uses a lot of material, with a fresnel lens the curvature is broken down into slices, and those pieces ...
I bought almost all parts from local store,also made some modules myself you can make one (i will give the links to my instructable its really low cost to make). So,here the list of the parts you need to collect :-HARDWARE: PIR motion sensor 5v Relay module(If you need to make …
How to Make a Simple Motion Sensor Led Light (Revisited) (PIR): Hi Again!Now, I am here with a new Model of PIR Simple Motion Sensor Led Light!The Previous Instructable had Portability Issues and a Resistor this Version i have made it more Compact and Easy to keep with a little improvement which i got…
You can in fact build your own motion sensor without spending too much. Motion sensors can be setup using ultrasonic transceivers, video cameras or microwave signals. In this tutorial, I’ll show you how to use the PIR motion sensor with a microcontroller. PIR is short for passive infrared which describes how the sensor operates; passive …
· The Out pin of the PIR sensor is connected with the base of the 2n2222 NPN transistor through a 10k resistor. the emitter of the 2n2222 NPN transistor is connected with the ground while the collector side is connected with one side of the relay coil and …
· Make a voltage divider with on the one end PIR output, and on the other end GND. Connect the Arduino to the middle Connect the Arduino to the middle Now you have to choose R1 and R2 so that 12 / (R1+R2) = 5 / (R2) and R1+R2 = 10..50K R1 = 22K and R2 = 15K Take care that the voltage on the digital is 4..5Volt not higher, so better round R2 downwards.
PIR (Passive Infrared) sensor is used to measure the infrared light radiating from the objects in its field of view; it detects the infrared energy released from animals and humans: when the detected energy is higher than a certain threshold level, PIR sensor will show an indication. The energy detected by PIR sensor is usually in the form of heat that is emitted by humans or animals. So PIR ...

Connecting PIR sensors to a microcontroller is really simple. The PIR acts as a digital output so all you need to do is listen for the pin to flip high (detected) or low (not detected). Its likely that you'll want reriggering, so be sure to put the jumper in the H position! Power the PIR …
· It has PIR sensor, but also a logic to process input signal from PIR and to treat it for the typical purpose of turnight the light on. For this purpose it is normal that after detection light will be on for 5-300s. Since your case is totaly different, you cannot use this sensor without modification. It is not problem with your program but the way sensor logic works. At the moment I got the ...
For proper calibration, there should not be any movement in front of the PIR sensor for up to 15 seconds (until pin 13 is turned off). After this period, the sensor has a snapshot of its viewing area and it can detect movements. When the PIR sensor detects a movement, the output will be HIGH, otherwise, it will be LOW.
