Today I brushed off my painting skills and followed a Christmas and winter-themed Bob Ross painting tutorial. The only problem is I'm not a great painter, and to put myself at even more of a ...

Like swimming pools, hot tubs need regular monitoring to ensure their water stays clean and clear. An average person might take a water quality reading once or twice a week using test strips, but such ...

Abstract: A wireless passive flexible sensor has been developed to measure the surface temperature of bearings and transmit wireless signals. The sensor employs a dielectric film sandwiched by a ...

Thank you so much for the project! When assembling the ESP32-DIV on a breadboard using pre-made modules, a problem arises with the incorrect operation of the display touch sensor. Chinese display ...

This system continuously monitors liquid presence at three key points in a tank (e.g., low, high, and an overall check point) using XKC-Y25-V non-contact capacitive sensors. An ESP32 (specifically, a ...

Abstract: For nonlinear state estimation in wireless sensor networks (WSNs) with partial measurement loss and random multistep delay (PML-RMD), a new robust loss and delay variational Bayesian ...

Ten years ago, Elektor published a simple Arduino-based AM radio transmitter for streaming audio to vintage receivers. While functional, the original design lacked polish and robustness. In this ...
