A Circuit That Can Sense the Change in the Temperature Value
This circuit measures the temperature using an LM35 temperature sensor and compares the input voltage using an ic op-amp with the info collected the circuit will turn on and off the relay.
Supplies
components:
• Breadboard
• Jumpers MTM
• 9V battery
• Battery clip
• Relay Module
• Voltage regulator L7805
• LED
• Resistor10K
• IC amplifier UA741CP
• 10K ohm potentiometer
• Temperature sensor LM35
Prepare All the Required Components.
Plug the IC Amplifier, the Potentiometer and the Temperature Sensor Into the Breadboard Then Wire the Second Pin of the IC Amp in the Middle Pin of the Potentiometer
Wire the Third Pin of the Potentiometer, the Fourth Pin of the IC Amp and the Third Pin of the Temperature Sensor in the Ground.
Wire the Third Pin of the IC Amp in the Middle Pin of the Temperature Sensor.
Wire the First Pin of the Temperature Sensor in the 5V.
Wire the First Pin of the Potentiometer and the Seventh Pin of the IC Amp in the 5V.
Wire The” Input” of the Relay Module in the Sixth Pin of the IC Amp, Wire the DC+ in the Anode of the Breadboard Then Wire the DC- in the Cathode of the Breadboard.
Connect the Resistor and the Anode of the LED in the Sixth Pin of the IC Amp the Wire the Anode of the LED in the Ground.
Plug the Voltage Regulator Into the Breadboard Then Wire the First Pin in Anode of Battery, the Second Pin in the Cathode of the Battery & the Ground and Wire the Third Pin in the Anode of the Breadboard.
