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 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 ...
In the neonatal intensive care unit, the most fragile patients in medicine are often the most heavily wired. Premature babies, some weighing less than a pound, can be tethered to a tangle of cables, ...
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: This letter presents a flexible and disposable humidity sensor based on Poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS). The sensing layer is developed by drop casting ...
