Description:

This kit is designed to control the piezo buzzer and LED by sensing the temperature accurately. When the sensing temperature is higher than the pre-set value, the piezo buzzer and 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 (10k Thermistor) of the LM358 is higher than the voltage at non-inverting input pin (10k Ohm Potentiometer), the LED and piezo buzzer will be turned on. The LED and piezo buzzer will be turned off when the input voltage at inverting input is lower (10k Thermistor) than the voltage at non-inverting input. The LED and piezo buzzer is turned on when the voltage from the thermistor is higher than the pre-set voltage at the potentiometer. For the 10k thermistor, when the sensing temperature increases, the voltage increases and the resistance decreases. For the potentiometer, the voltage of potentiometer is changed by tuning it. It is used to set the temperature level.

 

 

By adjusting the preset button, you can adjust the sensivity of thermistor:
