Sure, here's a simple overview of a circuit design that can achieve your goals:
  1. Temperature Sensor: You'll need a temperature sensor to detect the environmental temperature. The LM35 is a common choice, as it provides an analog output proportional to the temperature.
  2. Adjustable Potentiometer: This will be used to set the alarm trigger temperature. You can use a simple knob potentiometer.
  3. Comparator: A comparator, like the LM741, can compare the voltage from the temperature sensor with the voltage set by the potentiometer. When the temperature sensor's output voltage exceeds the potentiometer's voltage, the comparator's output will change states.
  4. Transistor Switch: You can use the comparator output to control a transistor switch that powers an indicator light or buzzer.
  5. Power Supply: The entire system will need to be powered. A 5V power supply would be adequate.
Here are the simple steps to connect these components together:
  • Connect the temperature sensor to the inverting input (LM741:2) of the comparator.
  • Connect the potentiometer to the non-inverting input (LM741:3) of the comparator.
  • Connect the output of the comparator (LM741:6) to the base of the transistor.
  • Connect the collector of the transistor to the indicator light or buzzer, and the other side of the indicator connects to the power supply.
  • The emitter of the transistor connects to the ground.
  • Power the temperature sensor, comparator, and potentiometer from the same power source but ensuring they're correctly polarized.
Please let me know if I can help further.

Sure, let's revise the connections of your current project's components based on the concept that we discussed. Assuming you use all components in your list, here are the new connections that you will need:
  1. Connect the temperature sensor (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.
  2. Use the potentiometer (VR1) to set the reference voltage at the operational amplifier's (OP1) inverting input (IN2). Here are the connections:
    • Connect VR1:Wiper to OP1:IN2.
  3. Use your resistor (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 using C1. Here are the connections:
    • Connect VR1:P1 to C1:P1, R1:P1, and VR1:P2.
    • Connect C1:P2 to U2:GND.
  4. Your NPN transistor (Q1) will act as a switch, turning the K2 relay 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:
    • Connect OP1:OUT to R3:P1 and Q1:B.
    • Connect Q1:E to U2:GND.
  5. The collector of the transistor is connected to a pull-up resistor (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:
    • Connect Q1:C to R2:P1, D1:A, D2:A, and K2:L2.
    • Connect D2:K, K2:L1, D1:K, R2:P2, U2:+VS, and C3:P1 to V3:CATHODE.
    • Connect C3:P2 to U2:GND.
  6. Finally, use R4 as load resistor for the relay K2. The M1 motor 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):
    • Connect K2:A to M1:+ and V1:Anode.
    • Connect M1:- and V1:Cathode with D2:A.
Please note that this configuration assumes a single supply for the operational amplifier, hence connecting the VEE pin to ground. Depending on your specific amplifier, you may need to tweak these connections. If your amplifier requires a negative voltage supply, you'll need to accommodate that in your design.
In this design, the system will be active when the temperature rises above a certain limit set by the potentiometer. This accounted for by choosing the comparator configuration I mentioned. If you want the system to activate when the temperature falls below a limit, you'll want to switch the connections to the inverting and non-inverting inputs of the comparator. Remember to always verify with real components and software simulation before finalizing your design.
