    Sensors


    Part Name Description Cost
     Load Cell 780gmMicro Load Cell (0-780g) - CZL616C. Needs Instrumentation Op Amp to get voltage high enough to read on A/D. $6.00
     Load Cell 100gmMicro Load Cell (0-100g) - CZL639HD.  Needs Instrumentation Op Amp to get voltage high enough to read on A/D. $7.00
    Instrumentation AmplifierAD623, a "single-supply" instrumentation amplifier with rail-rail output swing. High precision, suitable for amplifying Wheatstone bridge circuit in load cell in row above (see Figure 53 in spec sheet).
    Instructions to wire Instrumentation Amplifier with strain gauge sensor: Steve's Instructions
     $4.75
     Accelerometer 3-Axis Accelerometer ±1.5/6g  $8.00
     FSR Force-Sensing Resistor - 0.5" Circle. To start see basic voltage divider hookup.  For increased linearity and sensor info see op-amp hook up in:  Interlink Integration Guide, and Tekscan which has a similar product. Example product application. $7.00
     FSR Force-Sensing Resistor - 0.2" Circle. To start see an a basic voltage divider hookup.  For increased linearity and sensor info see op-amp hook up in:  Interlink Integration Guide, and Tekscan which has a similar productExample product application. $6.00
     Op-AmpMCP6271 Rail to Rail  Op-Amp. Lower cost op-amp suitable for amplifying signals at lower gains. The FSR in the row above can be connected as a voltage divider without an op-amp, or this op-amp can be used to increase sensor resolution. $0.55
     Capacitive Capacitive Touch Sensor $11.00
     Magnetic Switch Miniature Magnetic Contact Switch $2.50
     Magnetic Switch Magnetic Contact Switch $2.50
     Magnetic Sensor Hall Effect Magnetic Sensor $11.00

     6VDC
     Regulator
     The easiest way to power a servo is by connecting it to the Arduino 5VDC,
     but if you want 20% more voltage you can use a 6VDC Regulator, 1.5 amp.
     $0.50
