The circuit identifies and detects the temperature difference between two sensors and activates a relay when the temperature is not identical on these differently positioned sensors. By: Manisha Patel It’ll also enable you to detect a difference in temperature, although the temperature sensing devices can be set are discretely, using a potentiometer. Operational Details To […]

4 LED Temperature Indicator Circuit
The 4 LED temperature indicator circuit discussed here is very useful for getting a visual information regarding the state of temperature which is to be monitored. Circuit Operation In the circuit temperature status is displayed using four LEDs. – A green LED, indicating that the temperature is in the desirable level- Two yellow LEDs are […]
Temperature Triggered DC Fan Speed Controller
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 […]
