Use HC-SR04 on Arduino with Processing

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

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.

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.

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

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.

This project allows you to draw your own controller to be used with anything. It utilizes capacitive sensing and graphite's conductivity.

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

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 is based on Arduino radar (HC-SR04) which is digitally visualized using Processing.

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

An Android app-controlled, Arduino-based kit that receives and analyzes humidity and temperature data.

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.

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

First version of basic Home Weather Station.

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

Low maintenance, high output air pollution, sound pollution that put throughout the city without wiring.

Our objective is to design, build and implement in-the-field technology in an ecological way that generates environmental awareness.

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