Arduino - PIR Sensor. PIR sensors allow you to sense motion. They are used to detect whether a human has moved in or out of the sensor’s range. They are commonly found in appliances and gadgets used at home or for businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.
· Here’s the circuit schematics. The output pin of the sensor will be connected to pin number 8 on the Arduino Board and when an object will be detected the pin number 7 will activate the relay module and the high voltage lamp will turn on. For more details how the relay module works, you can check my Arduino Relay Tutorial. (Keep in minds that ...

· Hi everyone, I’ve been working on this small project for about 3 weeks, I’m stuck at this point and I could lose my job if I don’t get it to work properly :o so I will really appreciate your help. The idea is simple, pir senses motion, a timer starts decreasing, each time motion is detected the timer resets, when the time ends the relay acts as switch and the lights are turned off. Green ...

It shows the circuitry that uses an STM32F103C8T6 microcontroller to control a PIR sensor and relay switch to turn on a Light. Get the Fritzing source code for the above image HERE (in case you would like to modify it). Shown below is the code for the STM32F103C8T6 microcontroller to be used in the Arduino …
When there is any movement at the point where this security lamp is connected, it is detected by the PIR(Motion) sensor. Then a digital signal is generated through it. Afterward, it is obtained from the Arduino board and turns the relay module ON and OFF. That is, when a movement occurs, the bulb turns ON and turns OFF in a short time. We can control this bulb’s active time and sensing range ...

· If it still doesn't work, remove the relay and lightbulb, and change the line with: int Relay = 3; // connect the relay to pin 3 to int Relay = 13; // connect the relay to pin 13 Arduino has an onboard LED connected to pin 13 You can now see if the PIR sensor works by looking at the LED near pin 13 A lot safer experimenting with just low voltage before you hook it up to the mains.
· /* Sketch for Arduino relay control with PIR sensor PIN_RELAY contains the pin number to which the relay we will control is connected. PIN_PIR contains pin number with connected PIR sensor In the setup function, we set the initial position of the relay (closed). In the body of the loop function, we check the presence of a high level of the signal from the sensor using the digitalRead function ...
