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: Temperature is one of the most monitored items in many industrial and commercial applications. Internet of Things (IoT) temperature sensors are commonly small, low power, and able to measure ...

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 ...

The ESP32 keeps finding new jobs in my house.

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 ...

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...
