Product Description
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.
