U2) to the non-inverting input (IN1) of your operational amplifier (OP1), which will behave as the comparator in your circuit. This can be done as follows: Connect U2:Vout to OP1:IN1.VR1) to set the reference voltage at the operational amplifier's (OP1) inverting input (IN2). Here are the connections:R1) and the capacitor (C1) to form a low-pass filter, which will reduce the noise. It should be connected to your potentiometer at one end and grounded at the other usingC1. Here are the connections:Q1) will act as a switch, turning theK2relay ON and OFF based on the temperature. Connect the output of the operational amplifier (OP1) to the base of the transistor (Q1). The emitter of the transistor should be connected to ground. Here are the connections:R2) and the anode of the diode (D1). It's also connected to the anode of another diode (D2), which then connects to the relay (K2) and the input of the 5V voltage source (V3). Here are the connections:R4as load resistor for the relayK2. TheM1motor or the alarm should be connected to the COM and B of the relay. The other end should be connected to the 110V voltage source input (V1):
