PIR module usually requires an initial warm-up period for the sensing elements to come up to the operating mode. This usually takes not less than 30 seconds. So a 30 seconds delay is intentionally ...

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

PIR Sensor: The PIR sensor is an infrared based device which detects heat emitted from an entity. Due to it being passive, it does not take any energy to detect heat. The sensors are made of ...

When the PIR sensor no longer detects someone in range, it sends a notification over serial to a python script running on the PC to switch off the camera and microphone on Zoom (or another app).

Even though Attiny85 is fitting here, I opted for Digispark just because of its plethora of features like USB programming interface, on-board voltage regulator, and Arduino IDE compatibility. The code ...

It uses a motion-detecting sensor (PIR sensor) to open or close the door which detects the infrared energy omitted from human's body. When someone comes in front of the door, the infrared energy ...

While homemade masks are usually made from fabric [DesignMaker]’s version is much more to a hacker’s taste and includes 3D-printed parts, an Arduino Nano, PIR sensors, an SG90 servo, and some ...

Arduino RCWL 0516 RADAR Sensor Module Circuit Diagram The following image shows the circuit diagram for interfacing the RCWL0516 module with Arduino. The RCWL0516 uses just one pin to indicate motion ...
