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 ...

I’ve been testing out the RYB2340 Bluetooth module, and it’s honestly one of the simplest ways I’ve found to add wireless ...

It’s pretty easy to take a balloon, fill it up with helium, and send it up in to the upper atmosphere. It’s much harder to keep track of it and recover it when it falls back to Earth. If you’re trying ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the ...

Say goodbye to embarrassing parking mishaps. Whether you’re after added peace of mind during close-quarters maneuvering of your car or truck or you share a vehicle with a younger or less-experienced ...

Abstract: Near-field perturbation analysis of metamaterial-inspired split ring resonator (SRR) structures play a significant role in various sensor applications due to their high sensitivity. This ...

Abstract: The least-squares (LS) method is commonly employed to retrieve the 3-D wind field by joint detection with multiple sensors, but it tends to suffer from ill-conditioning and reduced accuracy ...
