Week 4: Sensor, Transducer & Actuator

TMP36 is a three terminal temperature sensor which generates an analog voltage at the output and is linearly proportional to the Celsius temperature. Which terminal act as an output?

• 1

• 2

• 3

Using the TMP36 is easy, simply connect the left pin to power (2.7-5.5V) and the right pin to ground. Then the middle pin will have an analog voltage that is directly proportional (linear) to the temperature. The analog voltage is independent of the power supply. So, if the voltage output voltage is 1V, what is the expected temperature in degree Celsius?

• 10 degree celcius

• 500 degree celcius

• 50 degree fahrenheit

• 50 degree celcius

What is the minimum voltage (+Vs) value to power up the temperature sensor (TMP36)?

• 5V

• 2.7A

• 3.3V

• 2.7V

A sensor is a device which converts one form of energy into another.

• Yes

• No

A transducer is a device which converts one form of energy into another.

• Yes

• No

Sensor is a device that converts energy into motion.

• Yes

• No

Light Emitting Diode (LED) is one example of Transducer.

• Yes

• No

An _________ is a device which converts an electrical signal into a mechanical force or motion.

A _________ is a device which converts energy from one form to another.

A _______ is a device which converts a physical quantity into an electrical signal for the purpose of control or measurement.
