What is the operating voltage of pressure sensor?(a) 3.5v(b) 1.5v(c) 5v(d) 3vI got this question in an interview for internship.My question is taken from Pressure Sensor topic in chapter Sensors of IOT

Answer»

The CORRECT answer is (d) 3v

For explanation: The pressure sensor has and ABSOLUTE pressure of 1.2 bar to 10 bar. The TYPICAL operating SYSTEM is 3v. With a supply voltage of 5V they offer sensitivities of between 15 mV/bar and 80 mV/bar, depending on type.
