Measuring Refrigerant Gases Sound Speed Using Arduino and App Inventor 2

The purpose of this Instructable is to build a portable device that can measure the speed of sound in refrigerant gases and use this data to identify them. The speed of sound in an ideal gas is related to two characteristics of the gaseous substance, its molecular mass (kg/mol) and its adiabatic constant (heat capacity ratio), or …

ITTT – Project Distance – Jurre De Groot 1D

HKU Assignment Hello all!Welcome to my HKU ITTT – “If This Than That” Project. For this assignment I created a simple eye test. The Distance Measuring Eye will give you a score based on the distance away from the eye. In this Instructable I will show you my thought process and the steps I took in creating this project. …

Measuring the Boiling Point of Liquefied Gases Using Arduino and PhyPhox

A substance that is in a liquid state is constantly evaporating or passing into the gaseous state (depending on the intermolecular forces and temperature). The pressure exerted by the gaseous molecules produced in this process is known as vapor pressure. The vapor pressure depends on the temperature in such a way that at higher temperature …

Arduino Project 11 (2D/3D pictures) – Measuring a water tank level v2 (HC-SR04 Ultrasonic Rangefinder/Arduino Uno/1.0)

1. Introduction: I made a water level sensor a little while a go to measure the water level in my underground rainwater harvesting tank. Thanks to the Jubilee I found time to finally setup the first part of my Arduino/Xbee wireless sensor network and the first sensor node was also meant to read from this …
