In this post I have explained about a simple yet sophisticated automatic emergency light circuit which can be considered “smart” due to the involved advanced features and an inexpensive design. The idea was requested by Mr. Lokesh. Technical Specifications Hi sir, I am so glad to see your interest towards electronic circuits. So eagerly waiting […]
Newly Updated Circuit Projects:
Automatic Evaporative Air Cooler Circuit
In this post we study a simple moisture sensor circuit which enables an evaporative air cooler to automatically restore the wetness level of its evaporative pad by detecting its moisture level and by activating the water pump accordingly. The idea was requested by Mr. Ankur shrivastava Technical Specifications sir could you please help me to […]
Push Button Fan Regulator Circuit with Display
A very interesting push button operated fan regulator circuit with LED display is explained in the following article, which can be built and installed at home for the suggested purpose. The idea was requested by Mr. Sriram KP. The Design Normally all fan regulators whether it’s a mechanical or electronic employ a rotary kind of […]
Simple Refrigerator Protector Circuit
This simple refrigerator protector circuit is actually a delay ON timer circuit which makes sure that whenever a power failure occurs or in case abrupt power fluctuations take place, the refrigerator is never allowed to switch ON instantly, rather after a delay of a few moments. Conventional Protection Features Today most modern refrigerators are equipped […]
Triac Phase Control using PWM Time Proportional
A triac phase control using a PWM circuit can be useful only if it’s implemented using a time-proportional format, otherwise the response could be haphazard and inefficient. In a few of of my earlier articles as given below: Simple Remote Controlled Fan Regulator Circuit Push Button Fan Regulator with Display Circuit Dimmer Circuit for LED […]
Surge Arrestor Circuit with Measuring Facility
In this post I have explained about a simple surge voltage protector circuit using a fuse and a triac crowbar circuit and also learn the method to record and measure the last maximum surge that could have destroyed the specified load in case the protection was not introduced. The idea was requested by Mr. Akram. […]
