Resistive (analog)

- sensor based on the variation of the resistance of a device

light-dependent resistors (LDRs)
- photoresistors, photoconductors
  • on left --> hermetic (CdS photoconductive cell in a flat lens package)
  • centre and right --> regular open cell
photoresistor
sample data sheets Perkin Elmer, Silonex
potentiometers
  • potentiometer with a linear or rotary sliding contact
  • joystick - dual potentiometers whose wipers are moved by the X and Y motion of the stick. The joystick connections are shown on the joystick.
  • force sensitive resistors (FSR™ from Interlink: Part No. 400 (0.2” Circle), 402 (0.5” Circle), 406 (1.5” Square), 408 (24” Strip)) - conductive polymer film sensor.  The point at which the force is applied behaves as a virtual pressure sensitive wiper.
strain gages  

thermistors (thermally sensitive resistor)

  • on left --> Thermistor PTC 12V 1 OHM 120C
  • on right --> Disc Type NTC Thermistors 20 Ohm

Electromagnetic Sensors

- sensor based on the variation in a magnetic or electrical field

Arduino library

Self-Generating Sensors/Actuators (analog)

- sensor yields an electric signal without requiring any supply. Effect is reversible so that the sensor can be used as an actuator to obtain nonelectric outputs from an electric signal input.

photovoltaic  
piezoelectric
  • piezoelectric sensor - material under strain generates electric polarization
  • piezoelectric actuator - electric voltage applied to the material induces strain
  • Microphone Omnidirectional 6.0X5.0MM -- EM6050P-433 [image, datasheet]
  • Microphone Electret Condenser -44 ± 2 db -- MD9745APZ-F [image, datasheet]
thermoelectric - thermocouples
  • thermocouple (sensor) - one in stock; probably Copper (+) Constantan (-)
  • Peltier Effect Cooler (actuator) - one in stock

Digital and Intelligent

- sensor whose output is digital

position encoders
  • incremental position encoders
  • absolute position encoders
  • DC motor with position encoder

RFID tag kit
RFID tags
Note: The code printed on the physical device is not exactly the same as the transponder code (the actual RFID number sent). Printed tag is in decimal and the RFID tag number is in hex. If printed tag is 0003886805 (decimal), convert this number to hex 3B4ED5. The actual RFID number will be something like 05003B4ED5.
