Light and Temperature Measurement with Audible and Digital Readout
Coolidge, Arthur W., III; Amend, John R.
South Australian Science Teachers Journal, 734, 37-42, Dec 73
Describes the application of an inexpensive relaxation oscillator circuit which uses a thermistor or a cadmium-sulfide photocell to affect the rate of an audio pulse output. It is especially well suited for qualitative and quantitative measurement of heat or light in classroom situations because of its clearly audible output. (Author/JR)
