May 15, 2019 - Automatic Wash Room Light controller using PIR Motion sensor and motion sensor Alarm Circuit using PIR Sensor. Hi in this video i will show you how to use pir motion without arduino. Just as in the case of the previous circuit, we will use a sensor to detect motion and the output of this sensor will be connected to a transistor. Cheap Electronics Electronics Basics Electronics Components Electronics Projects Hobby Electronics Electronic Circuit Projects Electrical Projects Led Projects Bartop Arcade. Optionally use a small screwdriver to adjust the sensitivity and time dials on the circuit board side of your PIR motion sensor. Parts Needed for Motion Detector Alarm Circuit. PIR stands for passive infrared. This is the second part of the car parking system. Infra red rays reflected from a static object will be in one phase, and the rays reflected from a moving object will be in another phase. This is suitable for low cost motion detection and alarm projects. The circuit diagram of the motion detector using NE555 timer is shown in Fig. The mode is selected by the jumper provided on the rear side of the sensor PCB. The PIR (Passive InfraRed sensor) detects the motion of person and gives short duration pulse output with the help of this sensor we can make the staircase light as Automatic one.The PIR sensor HC-SR501 is easy to use and comes with three standard pins (Vcc, out, Gnd) and also it has onboard sensitivity adjust and Time delay adjust, hence we can get desired output from PIR sensor.
