HC-SR501 PIR Motion Sensor PIR Sensor Module (Passive Infra-Red ) Sensor is an electronic semiconductor type sensor that measures infrared (IR) light radiating from objects in its field of view. This module detects and gives a trigger when there is a..
IR LED Pair 5mm (Transmitter and Receiver)This is a pair of 3 mm IR Transmitter and Receiver, operates around 940nm web-length. It is generally used for IR Remote Control and Non-touch Object Sensing (such as sensor for line following robot). Simply,..
LDR - 5mmLDR(Light Dependent Resistor) also known as photoresistor is a resistor whose resistance varies with the amount of light falling on it.This is a small LDR which can be used for making a light sensor, colour sensor, object sensor, line sensor..
