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 […]

Temperature to Voltage Converter Circuit
In this post I have explained a simple temperature to voltage converter circuit using IC LM317. The idea was requested by one of the dedicated members of this blog. Technical Specifications I have eurotherm TS200A temperature controller.this is thyrister based. This required 0-5V control voltage. I want one temperature control circuit when temperature is 25deg […]
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 […]
Programmable Temperature Controller Circuit with Timer
Here I have explained about a circuit configuration which produces adjustable sequential timing outputs for controlling a heater device through a simultaneously sequencing temperature controller circuit which can be also pre-programmed for acquiring the desired temperature levels across the sequencing time slots. The idea was requested by Mr. Carlos Technical Specifications I’m Carlos and I […]
Temperature Controller Circuit for Reptile Racks
The following article discusses a temperature controller circuit which can be used for controlling the temperature inside reptile racks. The idea was requested by Mr. Tom. Technical Specifications I’m looking to make a circuit to use to heat my reptile rack, I really like your incubator circuit, but do not have the electronics expertise to change it to suit […]
Make this Temperature Indicator Circuit with Sequential LED Display
In some of my earlier articles we have seen a few simple and interesting temperature indicator circuits, in this article we will try to upgrade one of them into a sequential form. All these circuits are useful in some or the other ways, however these are not equipped with step wise temperature level indicator arrangement […]
