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.

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.

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

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

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

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

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

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

A system using combination of an Aruino, several sensors and controlled via a ESP8266.

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

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.

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

A DHT11 connected to Blynk to read data

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

An SKU237545 pressure sensor.

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

First version of basic Home Weather Station.

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