This fan speed controller works by sensing the temperature of the engine and is accordingly used for the triggering. As the temperature increases so does the speed of the fan motor and vice versa. Circuit Operation Operation of the proposed temperature controlled fan may be understood as follows: The speed of the DC motor alters […]

Kiln Temperature Controller Circuit
A programmable sequential timer along with a triac dimmer is configured for making this kiln temperature controller circuit, further details are explained in the following article. The idea was requested by Mr. Joe. 220V Kiln Controller with Timer I’m hoping you have some time to have a crack at a design I’m after. I’ve been […]
Temperature Regulator Circuits using IC LM335
There are many cases where it is desirable to actively regulate the operating temperature of an electronic assembly. Sometimes, it is imperative to dissipate the heat generated by the components (this is the case for the majority of microprocessors in our modern PCs). On the contrary, it is necessary to artificially increase the operating temperature […]
Simple Greenhouse Temperature Regulator Circuit
In this post I have explained a simple electronic temperature regulator circuit which could be specifically used for regulating greenhouse temperatures. The idea was requested by Mr. Leo. Technical Specifications I am looking for a guide to build a basic temp regulator circuit. I have a solar charger bought from lidl,(SLS 2200 A1) which has […]
Temperature Controlled Relay Switch Circuit
In this article I have explained a simple temperature controlled relay circuit which can be switched ON/OFF depending on the temperature on its temperature sensor. Meaning, when the temperature on its temperature sensor rises above a set threshold point, the relay switches ON, and when the temperature drops below the threshold, the relay switches OFF. […]
Simple Temperature Indicator Circuits using Thermistors
A thermometer may be required for the precise measurement of temperatures. However, in many cases, an absolute value isn’t required and a relative estimate is sufficient. For example, the consumer may be alerted to the fact that an electric drill or vacuum cleaner is becoming hot, through a basic LED illumination, or through changing color […]
