- Solar
Insulation Monitor: An
inexpensive PIN photo diode and a 1ma meter movement form a simple sunlight
intensity monitor. The sensor should be placed inside a lightly frosted
glass hemisphere to minimize the influence of the sun’s angle on the sensor.
An adjustment resistor calibrates the meter for a full scale reading under a one
sun condition. An unshielded two conductor cable links the sensor to the
meter movement. The sensor and meter can be separated by up to 200 feet.
