A SSR is a solid state relay. It consists of a photo transistor and a triac, along with supporting circuitry. This isolates the 120vac load from the Arduino, so no damage from the high voltage AC can happen.
2020-10-31· PIR sensor HC-SR501 Arduino code and circuit. A passive infrared sensor is a device which detects the infrared rays emitting from humans, animals, or similar thermal ray source. An HC-SR501 sensor is a motion detector sensor that detects the motion of the infrared emitting sources, so if the thermal body doesn’t move, then the sensor doesn ...
2016-07-21· I'd like to use a PIR sensor (HC-SR501) to control the power to an Arduino Uno. Note that I'm not talking about using a PIR sensor as input to the Arduino and sensing the output pin from the PIR, I'm talking about using the output pin from the PIR to turn the Arduino itself on and off.
2015-04-03· So I'm running the PIR off the pin of the arduino, the gnd pin of the arduino, and then into input 9. I adjusted my code to the website but it still doesn't work. I want the relays to be on wh...

2020-04-18· Motion will be detected using a PIR motion sensor. If you are not familiar with the PIR motion sensor, you can read the following post: Arduino with PIR Motion Sensor; To control the lamp with mains voltage we’ll use a relay module in normally-open configuration. Safety warning
Learn how to use motion sensor to control relay, motion sensor triggers light. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to help you quickly get started with Arduino. Find this and other Arduino tutorials on
Then we declare the relay pin as an output (signal only go from Arduino) and we declare the PIR sensor pin as input (signal only goes into Arduino). Finally, we use digitalread to get a reading from the PIR sensor which is either 0 (no motion) or 1 (motion) and store it into the variable val.
PIR sensor has three terminals - V cc, OUT and GND. Connect the sensor as follows −. Connect the +V cc to +5v on Arduino board. Connect OUT to digital pin 2 on Arduino board. Connect GND with GND on Arduino. You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor …
Then we declare the relay pin as an output (signal only go from Arduino) and we declare the PIR sensor pin as input (signal only goes into Arduino). Finally, we use digitalread to get a reading from the PIR sensor which is either 0 (no motion) or 1 (motion) and store it into the variable val. Then we use an if and else statement to use this value which we stored to turn on/off the lightbulb ...
