This Circuit can compare the Light level in an area. It uses a PN Photodiode as the light sensor and IC CA3140 as voltage comparator. The circuit is ideal as the front end of burglar alarm circuits.

Voltage division is not just about ratios; it’s about control, clarity, and purpose. This little guide explores precision voltage dividers with quiet confidence, and sheds light on how they shape ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...
