passive infrared detector is amplified to a transistor BC547, the output of which at the collector is connected to pin 1 of the microcontroller. While any moving object is sensed by the PIR it develops logic high at its output which
What Is a BC547 Transistor? What Is an Epitaxial Transistor? What Is a 2N Transistor? What are the Basics of Transistor Substitution? Discussion Comments Bybagley79— On Aug 01, 2011 I still keep a transistor radio around the house and make sure I always have batteries for it. There have...
Some hobbyists, for example, use it to design and repair television and car application parts. It may also be used for linear, or regulated, power supplies, audio amplifiers, and low-frequency power converters. The 2N3055 transistor is based on an earlier model, the 2N3055 "power" ...
