LDR (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, color sensor, object sensor, line sensor, etc ....
Practical Distance that can be measured : 2cm to 80cm
Operating voltage : +5V
The Ultrasonic Sensor uses Ultrasonic waves to determine the distance of an object like Bats, hence it can be used as a distance measuring sensor. There are two Ultrasonic Transducers present in which one acts as a Transmitter which transmits a high...
This is a LDR sensor with Two Cadmium Sulphide (cds) Photoconductive Cells and spectral responses similar to that of the human eye. The Cell resistance falls with increasing light intensity. This photoresistor has application such as smoke...
