In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

The library gives control over up to 16 parallel working PIR devices over I2C. The idea for this library came up in a discussion about how to fully cover an area with PIR sensors without blind spots ...

Abstract: The Internet of Things (IoT) helps to create safe cities, businesses, and homes by allowing both public and private organizations to remotely and securely monitor facilities and public ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

Panasonic Industry unveils a new generation of passive infrared (PIR) motion sensing arriving with a clear message: performance no longer needs to come at the cost of design. A recently introduced ...

The PIR library implements a class to monitor 1 or more PIR sensors. The library supports default 8 PIR sensors per object, which typically are added in setup(). It is possible to add a sensor (pin) ...

While sensors and low power actuators occupy the lowliest level of an automation system, they often require a disproportionate amount of time and attention. Historically, each sensor added entailed ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

ABSTRACT: This study investigates the optimization of Fresnel lens designs using Zemax software, with a focus on minimizing beam divergence by controlling the output spot diameter on the image plane.
