Description:

This kit is designed to control the relay by sensing the presence of fire. Hence, it will decrease the resistance of the IR sensor. When the resistance of IR sensor is lower than the pre-set value, the relay and led 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 (IR sensor) of the LM358 is lower than the voltage at non-inverting input pin (10k ohm Potentiometer), the output pin will supply the voltage to the base of the transistor which will complete the led and relay connection to the ground then the led and the relay will be active. The LED and relay will be turned off when the input voltage at inverting input is higher (IR sensor) than the voltage at non-inverting input. The LED and relay is turned on when the voltage from the IR sensor is higher than the pre-set voltage at the potentiometer. For IR sensor, when the presence of fire can be detected, the resistance on the sensor will decrease. Then the voltage can flow through it. For the potentiometer, the voltage of potentiometer is changed by tuning it. It is used to determine the fire distance to be detected.
