Simple Temperature Based DC Fan Controller Circuit using Transistors
A simple but powerful temperature controlled DC fan controller circuit that uses transistors is really important for automatically cooling devices when they reach a certain temperature. This feature helps prevent overheating and improves efficiency. The circuit uses a thermistor to sense the temperature, which allows it to control the DC fan based on temperature changes. […]
Temperature Controlled Fan Circuit for Audio Amplifiers
Amplifiers create heat when they are in use and this heat can hurt how well they work and how long they last. To solve this problem, a special Temperature Controlled Fan Circuit for Audio Amplifiers has been made to keep the temperature just right. This circuit turns on the fan only when the amplifier gets […]
Simple Adjustable Thermostat Circuit using IC LM56
An electronic adjustable thermostat is an important part of controlling temperature and its often used in systems that heat or cool spaces. This specific circuit uses IC LM56, which is a low power chip that can switch temperatures on and off in two different ways. It helps control external transistors that manage the systems output […]
