Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...

Abstract: In this paper we present a way to reduce the standby power consumption of a PIR-sensor-based lighting device. Generally although a PIR-sensor-based lighting device will turn on when motion ...

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 ...

If you are thinking about building yourself a burglar alarm or you are thinking about Automating lights in your room, then you should definitely consider using an HC-SR501 Passive Infrared Sensor or ...

Abstract: Passive Infrared (PIR) sensors are commonly used in indoor applications to detect human presence. PIR sensors detect human presence by detecting the change in infrared radiation across the ...

Smart Bee Designs’ Bee Motion is an ESP32-S2 board with a PIR motion sensor, some GPIOs for expansion, and promising over a year of battery life under the right circumstances. If the name “Bee Motion” ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...
