Pir sensor based light circuit

PIR motion sensor light. Hello engineers, sometimes it's a bit difficult to go in a dark room and find a light switchboard to turn ON the lights and it's sometimes lazy too to switch on and off the lights when going in or out of the room each time or going through the garage or parking lawn.

PIR Motion Sensor Light Switch is designed using the arduino to deter the thief. Motion Sensor PIR Light Switch could be a part of automatic switch when a person come in PIR range.LED wall light in a brushed steel finish with built-in PIR motion sensor. • Sensor angle: 90° • 170 Lumens in a cool white (4,000K) LED colour temperature • Non-dimmable • IP44 Rated • Sensor timer: 20 secs. - 4 mins.
PIR Motion sensor based light with day/night intelligence. ... What I mean by light sensitivity is, The PIR logic works in AND condition. So when LDR connected, output status gets only high when LDR+resister's resistance matches the current expected light sensitivity AND there is movement detected by PIR. ... Provide same 12vdc from power ...The EEEkit Infrared Sensor Lamp Holder has 360-degree sensor detection and fits most 100V-250V sockets. The design has adopted sensitivity of the detector and integrated circuits. This motion sensor light switch led compatible is ideal for the basement, pantry room and storage room. It's suitable for various demands in your daily life.

I knew an OR gate could be used to trigger the LED (output) on either (or both, doesn't matter) condition: darkness or motion detected. The PIR outputs either 0 (no motion detected) or 1 (motion detected). But what about the light detection piece of the circuit? The LDR gives me an analog reading, and I needed a 0 or a 1 as inputs to the OR gate.

Pir sensor based light circuit

Circuit diagram of the PIR Motion Sensor Light and Switch based on SB0061 shown here can be used for security or corridor lighting in power saving mode. The 12V DC supply required for the whole circuit can be fed from any standard 12V ac mains adaptor/battery. Working of the circuit is simple and straight forward.

The LightHAWK® Dimming Dual Technology Wall Switch Sensor combines passive infrared (PIR) and ultrasonic (US) technologies with the additional energy savings of 0-10V dimming. A passive infrared sensor (PIR Motion sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. So, it can detect motion based on changes in infrared light in the environment.
