A beginner project utilising an Arduino and a BME280 sensor capable of giving you 4 environmental readings.

Building a rain sensing alarm with Arduino.

This is an image processing based fire detection and extinguisher system using Arduino and OpenCV.

In this project, use the YF-S201 1/2-inch water flow sensor to measure the water flow rate (L/min) and display it on an LCD.

+ LCD/OLED can be used to measure body temperature or to detect movement... in Celsius and Fahrenheit!

It is a miniature counterpart of radio altimeter used on commercial aircrafts to be used with RC aircrafts and multirotors.

It might be the simplest room temperature and humidity - no breadboard attached.

You can close your eyes, but you cannot close your ears.

This smart stick can help blind people walk on the street safely without any help.

In this tutorial, you will learn how to use a soil moisture sensor. Practical examples are also provided to help you master the code.

In this tutorial, you will learn how to calibrate and use MQ9 gas sensor with an Arduino board.

In this project I created a pretty simple digital level using a LCD screen and a gyro sensor.

Experimental system for Structural Health Monitoring (SHM), based on the Arduino.

It is a standard INA219 module but this has an isolated measured voltage from the MCU.

A modular orientation and acceleration data logger using a pair of ultrasonic sensors, RF transceivers, and a 1Sheeld.

Simple project to measure temperature (with two sensors) and humidity, and send them to the terminal (monitor) and also to a LCD display.

This little project will show you how to use a soil moisture sensor.

How to use the small module to measure distance for high frequency applications... or low.

Use three HC-SR04 ultrasound sensors and two battery displays to show you how close the obstacles are and from which side.

Now we can check out the depth of the sea level by using a pressure sensor (MS5803–01 BA) connected to an Arduino, and display sensor data.

How I built an Arduino energy monitor and data logger to collect energy data for different loads and plotted that data using Excel.

This Bolt IoT-based project shows how to build a metal detector alert monitor.

In this project, we're going to use the DHT11 humidity and temperature sensor to calculate the average temperature and humidity every hour.

Spending $1,000 on suspension repairs because the city failed to fix the potholes? This project makes sure that never happens again.
