Circuits Designed by Dave Johnson, P.E. :
Snow Depth Alarm -  The design of this system alerts a snowplow driver when the snow depth has exceeded four inches.  A visible red LED packaged in a 10mm package is pulsed at a rate of about 50Hz with 10uS pulses.  Twenty four inches away a phototransistor detects the light from the LED.  The LED and the phototransistor are housed in a section of inch PVC pipe, forming a waterproof seal. . . . Hobby Circuit designed by Dave Johnson P.E.-July, 2006
