What will happen if we supply a voltage of 25V to the Vcc of the IR sensor?

(a) Damage is caused

(b) Sensor will work fine

(c) Sensor will not respond for the time the voltage is applied

(d) Sensor will function normally

The question was posed to me in quiz.

Enquiry is from IR Sensor in division Interfacing of Sensors, Actuators, and Other Modules of Arduino

Best answer
Correct answer is (a) Damage is caused

Easiest explanation: The IR Sensors are mostly built to work on a voltage range of approximately 3.3V to 5V. Any voltage lower than that and the sensor will not be able to power on, but however any voltage significantly above that and the sensor may suffer permanent damage.
