Description:

This kit is designed to control the relay by sensing the temperature. When the sensing temperature is higher than the pre-set temperature level, the relay as output will be activated. In this kit, the LM358 operational amplifier is used as a comparator to compare voltage at the non-inverting input (+) and at the inverting input (-). When the voltage at inverting input pin (LM35) of the LM358 is higher than the voltage at non-inverting input pin (10k Ohm Potentiometer), the LED and relay will be turned on. The LED and relay will be turned off when the input voltage at inverting input is lower (LM35) than the voltage at non-inverting input. The LED and relay is turned on when the voltage from the LM35 is higher than the pre-set voltage at the potentiometer. For the LM35, when temperature increases, the voltage increases. For the potentiometer, the voltage of potentiometer is changing by tuning it. It is used to set the pre-set temperature level. 

 

Example project: Egg hatching incubator with temperature control with MB-03

 

By connecting the DC or AC fan via relay, a simple temperature controlling system can be done easily.
