How to Connect and Use RCWL-0516 Microwave Motion Sensor
In this article I will comprehensively explain about the RCWL-0516 a microwave proximity motion sensor which uses Doppler radar. Here, I will elucidate the following points: What is RCWL-0516 It is yet another type of proximity motion sensor which can detect if someone has entered into an area, and raise an alarm or take an […]
Audio Clipper and Compressor Circuits Explained
In this article I have explained using circuit diagrams how a clipper and a compressor circuits work to processes an input audio signal as per the required output signal. What is an Audio Clipper An audio clipper circuit is basically used to alter or restrict the amplitude (volume) of an audio signal. There are mostly […]
Electronic Measuring Tape Circuit using Ultrasound
Everyone is familiar with the mechanical measuring tape made of wood to measure human height. We offer you an original electronic version that operates based on the use of ultrasound. The circuit can be also used to measure distances between two surfaces or walls. Basic Working Ultrasounds are part of the range of sounds that […]
3 Laser Beam Controlled Circuits Explored
A compact, battery-powered transmitter emits a LASER beam when the control push button is activated. The beam is frequency-coded to provide a maximum level of reliability in transmission. The receiver can be located at a considerable distance from the transmitter (up to several tens of meters). The light beam, by definition, remains highly focused, and […]
Child Crying Monitor Circuit using Power Line Communication
In this child crying monitor circuit when the baby wakes up in their room, the parents are immediately notified, even if they are in another room of their home. A sensor detects the crying sound accompanying the wake-up. After appropriate processing, it sends a signal through the 220V power lines. The receiver, connected to any […]
