It means that I'm effectively getting three devices for the price of one, with the ESP32 acting as an offline soil moisture monitor, a Wi-Fi soil moisture monitor, and a Bluetooth proxy. Not bad for a ...

Here, we address this problem using carbon nanotube (CNT) field-effect transistors (FETs) in which the base device structure is lithographically fabricated before the deposition of gas-sensitive ...

Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

Rapid prototyping a GUI app with MicroPython + LVGL on the M5Stack Tab5, as demonstrated by our IoT weight-measuring project. I recently acquired an M5Stack Tab5 board for an upcoming project and ...

This important study introduces a new class of spectrally tunable, dye-based calcium sensors optimized for imaging in organelles with high calcium concentrations, such as the endoplasmic reticulum and ...

Over the last decade, the open-source movement has not only transformed the world of software, but also catalyzed a sweeping revolution in hardware tinkering. At the heart of this shift lies a ...

If you're new to EnviroDIY, I suggest you check out the Just Getting Started section of the documentation! This Arduino library gives environmental sensors a common interface of functions for use with ...

The objective of this study was to develop and validate a noncontact monitoring system for respiratory rate variability in rats under anesthesia using a 24GHz microwave radar sensor. This study aimed ...

An acid–base titrator connected to the Internet was developed for conducting remote investigative experiments. The experiment was broadcasted in a high school senior classroom, with the presence of a ...
