Overview
The QNET Mechatronic Sensors board features ten different sensors, including strain gage, piezo sensor, rotary potentiometer, pressure sensor, thermistor sensor, long range sonar and infrared sensors, short range magnetic field and optical position sensors and encoder; three types of switches – micro switch, optical switch; and push button, and two light emitting diodes (LEDs). Students learn fundamentals of interfacing with these sensors, including how to collect sensor data, calibrate, and use the data to identify natural frequencies of materials.
14 types of sensors:
Strain gage
Piezo film sensor
Rotary potentiometer
Pressure sensor
Thermistor sensor
Long range sensors: sonar and infrared
Short range sensors: magnetic field and optical
Micro switch
Push button
Optical switch
Encoder
Light Emitting Diodes
