In this tutorial, we are going to make “Dark Detector Circuits using different Light Sensors”. As we know that we always try to do and make things that save energy/power, a dark detector circuit can … Read more
phototransistor
IR or infrared radiations are electromagnetic radiation having wavelengths longer than those of other visible lights. Even though our eyes are very sensitive to light but we can not see IR radiations. Therefore it is … Read more
IR Detector Circuit using L14G2 Phototransistor
In this tutorial, we are making a very simple project of an Infrared Detector Circuit that detects infrared light. This circuit is using only three components an RS-276-145 phototransistors, 330Ω resistor, and a LED (Light … Read more
Infrared Detector Circuit using Phototransistor
A Phototransistor is a semiconductor device that is sensitive to light. It alters the current flowing between the emitter and collector, according to the level of light it receives. They are similar to a regular … Read more
