Code for arduino that makes fade in/out effect after receiving signal from switch, PIR sensor, etc. Default pinout: Pin 9 - main output. That's where you connect your LEDs. Of course you can change ...

The "pic18f16q41-pir-sensor" project highlights the advanced analog peripherals found on the PIC18-Q41 family of devices such as the Operational Amplifier (OPA) module, the 8-bit Digital-to-Analog ...

Wireless sensor networks are nothing new to Hackaday, but [Felix]’s wireless PIR sensor node is something else entirely. Rarely do we see something so well put together that’s also so well designed ...

The Bee Motion S3 is an ESP32-S3 WiFi and Bluetooth IoT board with a PIR motion sensor beside the more usual I/Os, Qwiic connector, USB-C port, and LiPo battery support. It is at least the third PIR ...

Abstract: Pyroelectric infrared sensors (PIR) are excellent devices to detect human/animal presence with a small form factor and rugged design, for cost-effective surveillance. They are widely used to ...

Abstract: The aim of the current paper is to describe the challenges faced during the development and deployment of a PIR sensor-based intrusion classification system in an outdoor environment. Some ...
