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

Code and explanation for getting directional and motion data from the raw sensor outputs.

Use HC-SR04 on Arduino with Processing

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

Dear friends welcome to another tutorial! Today we are going to build an interesting Arduino project which is using a fingerprint sensor ...

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

Here we use PIR sensor and Arduino to detect the motion of a hand. This detection can be used to operate electronic equipment.

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

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

Track ME is a "small" GPS, SD Card, and GSM Shield controlled by an Arduino Mega. Call me and get my location.

This project is about control of temperature in values of 23 and 25 grades and control for hysteresis using DHT22 and Arduino 101.

Smarter Home Energy Use with Open Source and Cheap Sensors.

A method in which waste management is automated. An innovative system that will help keep the city clean and healthy

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.

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

It is a device that measures CO2 levels, inside and outside temperatures, and humidity.

An SKU237545 pressure sensor.

The detector can detect a small metal coin at a distance of 15 centimeters.

If there will be no traffic on the other signal, one shouldn’t wait for that signal. System will skip that signal and will move on next one.

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

Sunglasses that serve an even more useful purpose than protecting the eyes of the blind. They can help them detect objects in front of them.

Let us predict the changes around us with Arduino

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