What kind of sensor is the ADXL-335 Accelerometer Module?(a) Passive(b

1.	What kind of sensor is the ADXL-335 Accelerometer Module?(a) Passive(b) Active(c) Radio(d) Pressure basedI have been asked this question at a job interview.The above asked question is from ADXL335 Accelerometer Sensor topic in section Interfacing of Sensors, Actuators, and Other Modules of Arduino
Answer» Correct choice is (b) Active For explanation I would say: The ADXL-335 sensor is an active sensor since it requires an active DC voltage source to function PROPERLY. On the contrary, an LDR can be said to be a sort of a passive sensor since it does not require the INPUT of current from an EXTERNAL source for its working.
