1. Hook up the PIR module to your Raspberry Pi This is pretty easy, you connect three Female/Female jumper cables to the PIR module. the other end of the cables go to these pins on the Raspberry Pi 3 pins: 5v goes to pin 2 on the raspberry pi The gnd (ground) wire goes to pin...
Configure a sampling sensor group, including the sampling path and filter criteria. When the configured sampling path meets the filter criteria, the device reports the sampling path to the collector in a timely manner. The following describes how to configure the sampling path and filter criteria...

When somebody walks between the light source and the sensor, the path of the beam is blocked briefly. The sensor registers a drop in light levels and sends a signal to the control box. More advanced security systems include passive infrared (PIR) motion detectors. These sensors "see" the ...
1. Get a Hidden Security Camera or Mini Camera Actually, one of the best diy hidden camera ideas is to get a spy or small security camera directly. It’s definitely much easier to hide a security camera if it is small with no wire at all. ...

Inputs are used to get information about what is happening in the real world. For example, you can check if the button is pushed or not by using thedigitalRead()command. Or you can check the temperature in the room by connecting a temperature sensor and using theanalogRead()command. ...
GPIO6 to GPIO11 GPIO14 GPIO15 Interrupt Pins All above-mentioned GPIO pins can be configured in interrupt mode to detect positive edge, negative edge, or level triggered. For more information refer to the following article: ESP32 Interrupts and Timers with PIR Sensor using Arduino IDE Strapping...
sensor's range. The sensor can also pick up the movement of inanimate objects as well, such a rolling ball, because as these objects move, friction acts on them, generating heat. This heat emits infrared radiation, which the PIR sensors may be able to detect if enough radiation is given ...
The PIR Sensor has three pins on it. Connect the Vcc and ground of the PIR sensor to the 5V and ground of the Arduino nano and connect theOUTpin of the PIR to the pin2 of Arduino Nano. Power up the relay module through Arduino and connect theINpin of the relay to pin3 of Arduino...
