We are showing how to use DS18B20 one wire water proof temperature sensor using Arduino.

With only an arduino board, two servos, and an hc-sr04, and some python, you can create a room scanner that is capable of showing depth!

A simple Electromagnetic Field Detector.

Basic weather system, in/out temp and humidity with heat index, dew point, pressure and weather prediction and time and date.

A project that displays the temperature and humidity of a room on your mobile in real time.

An easy-to-build and low-cost water quality monitor.

This parking sensor with Arduino is an easy project.

Trackers generate more electricity than their stationary counterparts due to increased direct exposure to solar rays.

A really economic street lighting system.

Simple and effective method (some police is using too) how to measure the side distance to an overtaking car.

This is an updated version of the fire alarm I made. it includes a gas sensor and an app for control

Seismic activity or "Vibrations of the earth" is measured using ProtoCentral's OpenPressure 24-bit DAQ System.

This is my first project, so please like the project and comment down below.

In this tutorial, I will be giving the basics for an ultrasonic thermometer and the idea behind it.

LPG leakage is monitored using arduino and MQ2 gas sensor module. the concentration of LPG particles are plotted using serial plotter.

Now we can check out the depth of the sea level by using a pressure sensor (MS5803–01 BA) connected to an Arduino, and display sensor data.

This project is about a simple inclinometer using Arduino 101 including temperature feature and auto rotation of display (upside down view).

An Arduino-based digital scale with HX711 and VFD display.

Learn how to detect Smoke and inflammable gases using an MQ-7 sensor.

This small tool checks brightness, and if there is fog or night out, will turn on without human action or worry.

"ADAFRUIT IO" makes IoT for everyone. Here we publish the data from a photo-resistor and a simulated GPS.

This device can remind user to drink water after a set time interval and can remind users when the water is at a right temperature for drink

They claim umbrellas own the ability to prevent from UV. We would like to know the fact and measure the UV value under umbrellas.

This is a simple prototype of light and reading distance keeper, built with Arduino Uno, ultrasonic HC-SR04, mini solar cell 0.5v, some LED.
