Control 5 Relay as per temperature value by using Arduino Circuit Diagram A temperature controlled relay switch is a useful device that can automatically control the operation of various electronic systems based on the ambient temperature. In this article, we will discuss how to make a temperature-controlled relay switch using the LM358 IC, BC547 transistor, 10k thermistor, 3V & 9V Zener diode, and 10k trimpot. These
The relay output of this temperature controlled relay circuit could be attached to either an alarm device, or any kind of heating system, or cooling system. For example the circuit could be used for switching ON a cooling fan as soon as the temperature is detected to be beyond a high threshold. Establishing the circuit design involves developing an accurate schematic that connects all its components. Circuit Diagram Overview: Begin with an orderly diagram that clearly depicts all connections. Connecting Temperature Sensor: Connect it directly to one of your microcontroller's input pins. Temperature Sensor Configuration:
Arduino - Temperature Sensor - Relay Circuit Diagram
In summary, the temperature controller circuit diagram with relay uses a microcontroller, temperature sensor, relay, and LCD display to control the temperature of a system. The microcontroller reads the temperature sensor's data and activates the relay to turn the heating or cooling system on or off based on the desired setpoint.
1. When the program starts, the relay is initially off (`LOW`). 2. Pressing the button triggers the following sequence: - The button state is read and debounced. - Once the button press is validated, the relay toggles its state (`ON` โ `OFF` or `OFF` โ `ON`). 3. The relay state is logged to the serial monitor for debugging purposes. This temperature controlled relay circuit is a simple yet highly accurate thermal control circuit which can be used in applications where automatic temperature control is needed. The circuit switches a miniature relay ON or OFF according to the temperature detected by the single chip temperature sensor LM35DZ. When the LM35DZ detects a
