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 ....
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...
Practical Distance that can be measured : 2cm to 80cm
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...
Inch product description 100 percent brand new and high quality using a wide voltage lm393 comparator with a mounting screw hole, easy to install using the sensitive type photosensitive resistance sensor the comparator output signal clean...
Input Voltage : 2 Volt - 5.5 Volts DC. Sensitivity can adjust by the capacitance(0~50pF). Have an external power-on reset pin(RST pin). After power-on have about 0.5sec stable-time, during the time do not touch the keypad, and the function is...
