Resistive

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

• on left --> hermetic (CdS photoconductive cell in a flat lens package)
• centre and right --> regular open cell

• 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.

thermistors (thermally sensitive resistor)

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

• NTC Thermistors Application Notes
• NTC disc thermistor
• PTC Thermistors Application Notes
• PTC disc thermistor

Electromagnetic Sensors

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

• UGN3503
• Hall Effect Sensing and Application

Self-Generating Sensors/Actuators

- 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.

• 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]

• thermocouple (sensor) - one in stock; probably Copper (+) Constantan (-)
• Peltier Effect Cooler (actuator) - one in stock

Digital and Intelligent

- sensor whose output is digital

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

• Silicon PIN Photodiode
• Silicon Photodiode, Blue Enhanced Photoconductive
• Silicon Photodiode, Blue Enhanced Photovoltaic
• Choosing the Detector for your Unique Light Sensing Application
• Light Measurement Handbook
• Photodiode/Phototransistor Application Circuit

• Hermetic Silicon Phototransistor (note data sheet is equivalent for the MRD310)
• IR Dark Phototransistor NPN can be used with IR Clr Emitter - high power
• Design Fundamentals for Phototransistor Circuits
• Photodiode/Phototransistor Application Circuit

RFID reader

RFID tag kit

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.
