This project implements a portable weather station using an Arduino Mega 2560, an ESP32 DevKit, a DHT22 temperature and humidity sensor, a rain sensor (both analog and digital outputs), and an LDR ...

Abstract: This work reports a flexible and disposable high-performance humidity sensor using the poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS) and graphene oxide (GO) ...

Compared to the Arduino Uno of old, modern microcontrollers are absolutely tiny — especially for the amount of processing power and I/O you get. But if you need something really small, like ...

Our team designed and built a fully functional prototype from the ground up. We handled the firmware, the PCB layout, the 3D ...
