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 ...

GHz phased array radar system featuring Pulse Linear Frequency Modulated (LFM) modulation and based on an AMD Artix-7 FPGA.

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 ...

Getting your Trinity Audio player ready... Regional Transportation District officials are promoting public transportation as a safe and convenient way to reach downtown and the Denver Broncos’ playoff ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually requires a ...

Getting your Trinity Audio player ready... For potential metro Denver public transit riders bothered by open illicit drug use and people who lack housing taking shelter on buses and trains, Regional ...

Abstract: The residence time-difference (RTD) fluxgate sensor is critical for high-precision magnetic field measurements in applications such as unmanned aerial vehicles (UAV) magnetic surveying, ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to 20mA ...
