PIR / IR Sensor

This is a simple to use Arduino motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low. This sensor checks for infrared heat in its detecting angle. The human body, pets, and several other things emit energy that the sensor is looking for, it compares with the snapshot, and if there is a recent change it triggers.

Get on with your Home alarm security audit gear and experiment with this sensor to get a better understanding of its efficiency and working method. Infrared motion detectors are common all around the world for many different appliances. It’s great for an Arduino or home automation project that requires automated motion feedback. Commonly found on automatic trigger light systems, where lights are ON when someone is in range and OFF when no one is around. Save power or trigger other actuators like a door opener or pet feeder.

This is a PIR (passive infrared motion) sensor designed to work with Arduino and Raspberry Pi. It allows you to sense motion, it is commonly used to detect whether a human has moved in or out of the sensor’s 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.

This is a High-accuracy good quality IR sensor from Waveshare. Infrared Obstacle Avoidance IR Sensor Module (Active Low) has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The onboard LM393 voltage comparator circuitry does the processing and the green indicator LED comes to life.

The module features a 4 wire interface with Vcc, GND, DOUT, and an AOUT pin on its tail. It works fine with 3.3 to 5V levels. Upon hindrance/reflectance, the output pin gives out a digital signal (a low-level signal). The onboard preset helps to fine-tune the range of operation, the effective distance range is 2cm to 30cm.
