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

Use HC-SR04 on Arduino with Processing

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

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

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.

An SKU237545 pressure sensor.

Track your face using OpenCV's facial recognition.

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

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

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

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

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

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

Track the sun in X and Y with this simple Arduino project.

Real-time pH and salinity monitoring with LED indicators.

Want to measure solar radiation but cant afford a Pyranometers? Well, make your own device with your Arduino board using this guide.

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

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).

this project uses a touch sensor to turn on and off an led on pin 13.

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

A system to maintain the pH level of a sample within a defined range.
