IoT Based AC Fan Speed Control using Smart Phone with NodeMCU and Google Firebase In this article, we are building an AC Fan Regulator Circuit, which is able to control the speed of the fan by restricting the flow of current to the fan. The term AC Ceiling Fan Regulator is a mouthful, hence we will simply call it a fan regulator from now on. A fan regulator circuit is a crucial component that is used to increase or decrease the speed of an AC Fan/motor… |

Building a Compact and Low Power Solid-State Relay to Control AC Home Appliances using ESP8266 for IoT Applications Relays are common in many switching circuits where controlling (turning ON or OFF) an AC load is required. But due to the electromechanical characteristic, a mechanical relay has a self-life, and also it can only toggle the status of the load and cannot perform other switching operations like dimming or speed control. Apart from this, an electromechanical… |

All About Transformer Protection and Transformer Protection Circuits Transformer protection is crucial as transformers are one of the most critical and expensive components of any distribution system. It is an enclosed static device usually drenched in oil, and hence, faults occurring in it are limited. But the effect of a rare fault can be hazardous for the transformer, and the long lead time for repair and replacement of transformers makes… |
