3 Laser Beam Controlled Circuits Explored

Last Updated on January 20, 2025 by Swagatam 12 Comments

laser door bell circuit

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 […]
