Q3) A device has two sensors, one measuring the temperature and the second measure the current. The temperature sensor is a thermocouple gives output signal considered linearly proportional to the temperature between 0V and 20 mV for 0°C temperature and 150°C, respectively. Whereas, the current measuring sensor gives voltage proportional to the current between OV and 1V for 0A and 2A ,respectively. The temperature should not exceed 100°C and the current should be less than or equal to 1.2 A. The device should work only if the two mentioned conditions are both true. Design a circuit to make the device works according to those conditions, the device relay should get 5 V to switch it on, and OV make it off.
