How to Build a Motion Detector Circuit

The PIR motion sensor is a sensor which detects movement through picking up infrared waves. Being that a person emits infrared waves, the detector is able to detect these waves and react, according to the how the circuit is designed to react. The sensor can also pick up the movement of inanimate objects as well, such a rolling ball, because as those objects move, friction acts on them ...

HC-SR501 PDF - PIR Sensor, Motion Detector

· PIR Sensor (HC-SR501) Introduction Passive Infra-Red (PIR) sensors are used to detect motion based on the infrared heat in the surrounding area. This makes them a popular choice when building a system to detect potential intruders or people in general. These sensors can take for 10-60 seconds to warm up, so try to avoid motion during that time.

Motion-Sensing Security Light Circuit -

When PIR sensor module detects motion, T1 whose gate is linked to the PIR sensor module, cuts off T2, so that the light source turns off. However, C1 is discharged fairly slowly through R4, so that the light source is not turned off immediately (goes out slowly). This turn-off delay may be varied by altering the values of C1 and R4.

PIR Motion Sensor -

PIR Motion Sensor. Motion sensing is the detection of the change in position of an object relative to its surroundings or vice versa. There are many kinds of motion detector methods: infrared, optics, radio frequency, sound, vibration, and magnetism. These methods differ from each other because each of them uses a different medium and detects ...

PIR Sensor Circuit and Working with Applications

PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output. It is very simple and easy to interface the sensor with a microcontroller. The output of the PIR is (usually digital output) either low or high.

PIR Sensor Based Motion Detector / Sensor Circuit Diagram

· Passive Infrared Sensor (PIR) is very useful module, used to build many kinds of Security Alarm Systems and Motion Detectors. It is called passive because it receives infrared, not emits. Basically PIR sensor detects any change in heat, and whenever it detects any change, its output PIN becomes HIGH. They are also referred as Pyroelectric or IR motion sensors.

PIR Motion Sensor - Adafruit Industries

· PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors…
