WebJul 29, 2012 · The easiest way to measure a resistive sensor is to connect one end to Power and the other to a pull-down resistor to ground. Then the point between the fixed pulldown resistor and the variable photocell … WebA) R1 is a CdS photocell in series with a 1000-ohm resistor. The 5 volts form VCC divides across R1 and R2 in proportion to their resistance. For example, if R1 = R2, one would read 2.5 volts across each component. Using a DC voltmeter (black lead on ground, red lead at V) one will read 2.5 volts.
