Water is a precious resource. Millions of people do not have access to clean drinking water, and as many as 4000 children die from water contaminated illnesses every day. Yet, we continue to be wasteful with our resources. The overarching goal of this project is to motivate more sustainable water use behavior and raise awareness

Product Description This is a light sensor that I’ve been waiting for, for a long time. If you use photo cells or phototransistors, or other light sensors such as the useful TAOS TSL series, you know that every one leaves something to be desired. In robotics for example, sensors either tend to saturate in dark

LPG sensor using Arduino with alarm and cutoff. A simple LPG sensor using Arduino is shown in this article. This circuit indicates the amount of LPG in the air. The circuit sounds an alarm and trips a relay when the concentration is above a predetermined level. MQ2 is the gas sensor used in this project.

Meet Easy Pulse: A kit that includes all it needs to make a DIY heart rate sensor. Although it is not built using an Arduino, it is still open and easy to build. From the site: “This project is based on the principle of photoplethysmography (PPG) which is a non-invasive method of measuring the variation

Description This module can be used to measure temperature using RTD (resistive temperature detectors) temperature sensors. It produces an analog voltage that is proportional the temperature of the probe. The module contains a multiplexer to enable measurement of up to 4 temperature probes. Design RTD Temperature sensors change their resistance with temperature. The resistance change

The MQ-3 is an alcohol gas sensor that is available for about $5 from Sparkfun, Seeed Studio, and others. It’s easy to use and has sparked the imagination of anyone who has dreamed of building their own breathalyzer device for measuring the amount of alcohol in the human body. I got an MQ-3 sensor a

Tyree (he wears a tie and he has tires) actually smiles after he bumps into something (see video). Using an Arduino motor shield, he detects obstacles using the “more current into the motor means something is in the way” principle. Tyree started out as a sketch and morphed into a real object thanks to Autodesk’s

ArduSensors are open source plug-in-play sensors for Arduino. These were originally made for beginners to get started with Arduino, a very cool electronics prototyping platform, but anyone can use them. I still play around with them all of the time, and I bet a ton of people that are experienced with electronics still love them.

Update: New interface – look at the last step. Credits: Arduino sensing done by DZL, Processing sketch and Instructable done by Mads Hobye. Disney Research lab designed a novel way to detect touch. You can see a video of their demo here: I had the honor to meet them at CHI2012 in Texas and I discussed with them

This lab most recently revamped by Edgar Berdahl and Wendy Ju. Chris Carlson, possibly Bill Verplank, and others have likely contributed. For this lab you need your Satellite CCRMA kit, a laptop computer with Ethernet adaptor to program it, and some headphones with a mini 1/8″ (2.54mm) stereo jack. You are also invited to bring
