The circuit shown in Figure can be transmitted over a long distance signal detected target. PC1 infrared diode and phototransistor pair, when a target object or irradiating light barrier diode phototransistor, the phototransistor is turned on in the turned off, and through amplification and second infrared diode and phototransistor and power amplifier for transmission to the load (alarm or lights), the second of the infrared diode and phototransistor pair from the fail-safe action. Infrared remote monitoring circuit diagram shown in Figure:
