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 ...

The ESP32 keeps finding new jobs in my house.

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 ...

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 ...

Continuous glucose monitors have become popular among diabetics and those who need to track their glucose levels. These devices are painless and can easily sync up to an app on your smartphone or ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
