Abstract: A high-sensitive wireless and passive surface acoustic wave (SAW) humidity sensor operating at 433 MHz was designed and developed. SiO2 thin film with large specific surface was employed as ...
Researchers develop a stretchable battery powered by air moisture with a built-in self-destruct feature for IoT devices.
Researchers from North Carolina State University and Rice University have created a nontoxic, stretchable battery that operates by extracting moisture from the ambient environment—even in climates as ...
This is the SparkFun Arduino library for the Texas Instruments TMAG5273 low-power linear 3D Hall-effect sensor with I 2 C interface. This SparkFun Arduino Library for the Texas Instruments TMAG5273 ...
Can an ESP32 detect people without cameras or motion sensors? Discover how Wi-Fi signal disturbances, CSI, and smart DSP enable real-time occupancy and mov ...
The ESP32 keeps finding new jobs in my house.
ESP32s are surprisingly good AI lie detectors.
Abstract: In this study, the degradation of copper wire under different temperatures and humidity levels is investigated. High temperature and high humidity accelerated stress tests with a cumulative ...
