In this article we study the microwave sensor IC KMY 24 and try to understand its main features and its pinout implementation details. How Doppler Sensor KMY24 Works The KMY24 […]
Sensors and Detectors
Simple Digital Clock using LM8650 IC Circuit
The digital time clock explained here is a circuit which most electronic amateurs would love to make. You might have heard about digital clocks made from clock ICs such as […]
Differential Temperature Detector/Controller Circuit
The circuit identifies and detects the temperature difference between two sensors and activates a relay when the temperature is not identical on these differently positioned sensors. By: Manisha Patel It’ll […]
Tuned Infrared (IR) Detector Circuit
The article is a continuation of the earlier post where we tried to find a solution for creating unique infrared IDs for trains in a model locomotive system. Here I […]
Simple Shadow Sensor Alarm Circuit
This shadow detector circuit operates using two LDRs and effectively detects the difference between the light levels and triggers a loud audible warning siren. In circuits which uses a single […]
Morse Code Flasher Circuit for Lighthouse
In this post I have explained a simple morse code lamp flasher circuit which may be used for model lighthouse signalling applications. The idea was requested by Mr. Frank Gardner. […]
