Abstract

PURPOSE:To automatically cope with a circumstance variation of an installation place, by detecting an external light and setting it as a comparison level. CONSTITUTION:A detecting signal of an infrared ray detecting means 101 consisting of a pyroelectric type infrared-ray sensor, a junction type FET for outputting a temperature change given by an incidence of infrared rays, as a signal, and a resistance, and a detecting signal of an external light detecting means 103 consisting of a CdS whose electric resistance value is varied in accordance with brightness, and a resistance are inputted to a control means 104 consisting of a microcomputer, respectively, and compared with each other. In such a way, the circumstance variation of an installation place, etc., can be decided automatically, therefore, the detecting sensitivity adjustment for preventing a malfunction becomes unnecessary.
