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.

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

Accurate signal conditioning and high-resolution measurements are no longer limited to industrial or instrumentation applications. Designers of portable consumer- electronic equipment also need to ...

The P0463 code indicates that your car’s engine control module (ECM) is receiving a voltage signal from the fuel level sensor that is higher than expected, which suggests that the system believes the ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...

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 ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine ...

We were recently tipped off to quite a resource — on the Texas Instruments website, there’s a page where you can view and download a compendium of analog sub-circuits. Individual circuits can be ...
