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 ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or ...

A quantum net for dark matter: A distributed intercity network of quantum sensors is placing additional constraints on the parameters that axionic dark matter could have. (Courtesy: USTC) A new of way ...

Abstract: A long-distance, strong-misalignment tolerance seawater capacitive power transfer system with two insulated electric-field couplers and single-wire for underwater sensors is proposed in this ...

LaserEye is a security monitoring system utilizing ESP8266 board, a laser, and a sensor to detect trespassing. Integrated with Firebase Realtime Database, it provides real-time notifications through ...

This program written with Arduino Code running on ESP8266 (Wemos D1) is just a test to access, read status and control Tuya compatible WiFi Smart Devices (Plugs, Switches, Lights, Window Covers, etc.) ...

Here we are designing a very small, tiny CAN network sensor that can be attached to any vehicle. It detects motion, accidents, and all vehicle activities in real time. It can also be modified to act ...

Abstract: In this article, we introduce a novel group of space-time-frequency codes based on multiple trellis coded modulation (MTCM). These codes are originally designed without accounting for the ...
