1121_0 - Voltage Divider

This adapter lets you interface with all sorts of non-Phidgets resistance sensors, just dial in the resistance you want and away you go.
Availability: 2 in stock

Manufacturer: Phidgets

The 1121 provides an interface to non-Phidgets resistance sensors such as: Force-Sensing Resistors (FSR), light sensors, thermistors (heat sensors), and bend sensors. The Voltage Divider eliminates the need to connect a resistor to an analog input by putting a high precision potentiometer on the board to allow the adjustment of the 'fixed' resistor. The interface to the variable resistance sensor is a convenient terminal block.
