Summary
The system contains an IR transmitter, an IR receiver/RF transmitter, and an RF receiver/alert beeper. Two IR LEDs in the transmitter transmit a pulsed beam of invisible infrared light to the receiver, which contains an IR phototransistor. The phototransistor detects and amplifies the pulse-modulated IR beam.

Frank: I have "never" seen a schematic with capacitor values shown as "0.002F". To me, this would read as 0.002 Farads!!! Is this what you mean? Or, is this "0.002pF" or "0.002uF"? Is this how you show capacitor values in whatever country you are from? While I have seen capacitors in the "Farad" range, they are usually in values of 10-Farads to 100-Farads or so and have been used in automotive audio amplifiers. Can you clarify these capacitors for me please? THANKS!!! JBW
