SIMPLE WIRING & SCHEMATIC AUDIO RADIO STREAM (AVR)

 

MULTI SENSOR (DARK LIGHT & MOTION)

Rangkaian ini menggunakan 2 buah sensor yakni sensor cahaya dan sensor gerak. Cara kerja        rangkaian ini adalah; bila kondisi ruangan tempat modul multi sensor diletakkan dalam kondisi gelap atau kurang intensitas cahaya diruangan tersebut serta ada gerakan yang terdeteksi oleh PIR (Pasive Infra Red) maka rangkaian PIR akan memberikan perintah ke sensor cahaya untuk meng on relay dan  menyalakan lampu. Waktu on atau off delay nyala lampu dapat diatur pada trimpot di PIR motion sensor.

Dalam kondisi ruangan serta lingkungan dengan intesitas cahaya yang cukup mengenai modul terssebut serta ada gerakan yang terdeteksi oleh PIR sensor maka lampu tersebut tidak akan menyala, atau rangkaian LDR (sensor cahaya) tidak memberi perintah meng onkan relay/lampu.
