This video will illustrate the working principle of the Water Quality Monitoring and Notification System.

Use HC-SR04 on Arduino with Processing

This system monitors the moisture of soil and waters it by 5v DC motor based water pump when needed.

This is the first generation of my Arduino based mini-weather station with Wi-Fi connection, which is able to post data publicly online.

Long-range wireless sensor based on Whisper Node capable of running for over a year on a single CR2032, transmitting data every 60 seconds.

The ESP system make it easy to recognize gestures you make using an accelerometer.

This project detects the various obstacles and plots them on a graph.

We built a stylish and useful humidity and temperature sensor for our home workshop that uses color to alert us to big swings in humidity.

We connect a VL53L0X Laser time-of-flight sensor to an Arduino to measure the liquid level in a tank using ToF ranging.

LIDAR stands for Light Detection and Ranging. LIDAR is used for many applications including 3D scanning, mapping, laser guidance, etc.

An SKU237545 pressure sensor.

We are going to learn a technique for building gesture-controlled laptops or computers using the power of Arduino and Python.

Create an OLED screen that shows the date, time in digital and analog format, temperature and humidity.

Anemometer or a wind speed measuring device is a common weather station instrument. It was costly online, so I built one!

You activate the bomb by plugging it and hold button to defuse.

Hazardous Gas leak detection system employ an audible alarm to alert people and lock all the air tight gates.

CAN bus hack for reading the battery diagnostics form an electric car.

I will explain how connect Arduino with Vibration sensor and LED.

A blind assist tool that provide obstacles notification and GPS location to the guardian / authority via SMS.

Reads and stores in SD card, the temperature and humidity values over time.

Arduino project to detect lightnings using electromagnetic radiation with frequencies from 7-9kHz.

This project will calculate the water content of soil around a plant by measuring the dielectric constant.

The objective is to find an easy way to implement RS485 on an Arduino Uno, then to adapt it to an ESP8266.

I built an Arduino Weather Station. It uses a DHT 11 (it will also work with DHT21 DHT22).
