PIR Motion sensor /detector module HC-SR501 with relay circuit schematic Room automatic light

NOTE: There is lot of different type of relays. In this video I'm using 12V relay module and it works good. But I have another relay that look similar to this that I'm using in this video and also for 12V and that relay won't work with this circuit. Only difference between that two relay is resistors with different values. If you want to be sure that this circuit will work it's better to use 5V relay module. In this video I will show how to use motion sensor only with relay module. With this circuit we can control high voltage and high current devices up to 250V and 10A. The PIR sensor (Passive Infrared Sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used to sense movement of people, animals, or other objects. They are commonly used in burglar alarms and automatically-activated lighting systems. This module is small size and easy to use. It is just a single bit output (High or Low) and compatible with any types of microcontroller. Specification Product Type: HC--SR501 Body Sensor Module Operating voltage range: DC 4.5-20V Quiescent Current: up to 50uA Level output: High 3.3 V /Low 0V Trigger: L cannot be repeated trigger/H can be repeated trigger(Default repeated trigger) Delay time: 5-200S(adjustable) the range is (0.xx second to tens of second) Block time: 2.5S(default)Can be made a range(0.xx to tens of seconds Board Dimensions: 32mm*24mm Angle Sensor: les than 100 ° cone angle Operation Temp: -15-+70 degrees Lens size sensor: Diameter:23mm(Default) Applications: Switch Motion sensor Thief-guarding system Industrial automation RELAY Specification: Maximum load: AC 250V/10A, DC 30V/10A Trigger current: 5mA Working voltage: 12V Module size: 50 x 26 x 18.5mm (L x W x H) Four mounting bolts holes, diameter 3.1mm Module interface: DC+: positive power supply (VCC) DC-: negative power supply (GND) IN: can be high or low level control relay Relay outputs: NO: normally open relay interface COM: Common Interface Relays NC: normally closed relay interface High and low level trigger options: It is low level trigger when jumper connect to LOW pin It is high level trigger when jumper connect to HIGH pin Please subscribe.
