Hi,
I want to know if a glass bead thermistor would be light dependent.
I am directing a laser beam into a Light Dependent Resistor to measure turbidity in liquid samples, but am finding that there is heating of the LDR. This is causing the resistance reading of the LDR to change and give a false reading. I have glued a very small grass bead Thermistor to the back of the LDR and hope to measure the rise in temperature of the LDR when it is illuminated by the laser light. I am currently painting the Thermistor black and trying to see if it has any light sensitivity.
What do people think.
thanks
