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 ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...

Build a Speed Sensor using Arduino with IR speed sensors to accurately measure the speed of moving objects. This tutorial covers circuit design, sensor calibration, speed calculations, and optimized ...

Furthermore, PIR sensors are susceptible to false detections when non-human objects enter the sensor’s view, adding to their limitations. When embarking on a new sensor design, it’s worth considering ...

Arduino HomeSec System integrates sensors for intruder detection, distance measurement, sound monitoring, and vibration sensing. It sends SMS alerts via SIM900A GSM module, enhancing home security ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects.

Pinout diagram The board is somewhat similar to the company’s Bee S3 board which comes without a PIR motion sensor and fewer I/Os. The Bee Motion S3 can be programmed with Arduino, CircuitPython, and ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body.

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” ...
