Note: Draw the schematic and code for each of the following question. All question carries equal marks.

1. Design heat control system as follow.

Design a system to maintain the temperature of the system at 37 degree celcius.A temperature sensor is attached with the Arduino analog input. A fan (220 volts) and heater (220V) is placed in a room. If temperature is greater than 37 degree, turn the fan on and if temperature is less than 37 turn on heater.

Take the temperature reading after every 10 minutes.

*Hint: Use relay to turn on Fan and heater.Control the realy using Arduino.

Expert Solution

we are using arduino, two spdt relays and temperature sensor TMP36 to obtain the solution to the problem presented and for simplicity lcd screen is not used to display the temperature.
