| Summary: | Infrared motion detector is one of the common motion detectors that used in the security system. The infrared motion detector are divided into two with is active and passive. This project is conduct to design and develop a face to face active infrared motion detector. This detector is design to replace reflector to reflect that infrared that emit by emitter. To design the circuit, the circuitmaker6 student software is used; it will make the designed process easier. Then, the designed circuit will develop and the output voltage for each circuit was measured and recorded. From the data the attenuation was calculate. The calculate attenuation then was analyses and it show that the increasing of the distance make the attenuation increases, for distance 1cm, 4cm and 7cm, the attenuation are 0.58dbm, 1.5dbm and 1.97dbm . The attenuation is the loss of the energy. So to avoid it, the best way is reduce the distance. |
