Open Source Server Room Monitor using Arduino

This server room environmental monitoring system is a low cost high performance device with the same onboard features as commercial devices costing hundreds of dollars more. In addition to a low cost platform we will provide low cost sensors for many important devices to insure your equipment stays safe and sound. Full instructions are available at sproutboard.com as well as several kits to create some very ...

Sensing Squeeze using Arduino

I’m researching squeeze sensing as a mode of tactile interface. Here I will cover the process of developing a squeezeable sensor and the firmware/software concerns associated with interpreting the data from the sensor. This fulfills the “sensor project” for my class called Computational Principles in Media Arts taught in AME at ASU by Todd Ingalls and Hari Sundaram. First off, how do we sense “squeeze?” Peo ...

Cat Repelling PIR motion sensor (covert) speaker box alarm using Arduino

This is a PIR motion sensor device that works with the arduino uno. In order to make it covert enough to be placed in multiple settings and portable enough to fit most places, I decided to make the case for it appear as a speaker. The inspiration for this project: My cat is a jerk. One of his favorite things to do is to alarm me that he is hungry every morning at 4am by sitting on my dresser and knocking ra ...

Geiger Counter with Touch Interface!

There are quite a few geiger counter instructables. The difference with this one is that I wanted to give it a modern interface, similar to smart phone touch screens, that anyone would feel comfortable using. The reason for this is that I want to use it as an educational tool to teach kids (and interested adults!) about radiation and how it is a natural part of the environment. Check out the video to see wh ...

Super Secret Lock Box w/ Capacitive Touch

Hey everyone, I wanted to share a project I just finished up. I built a super secret locking box for my girlfriends little brother. He has a knack for creative lego building so I thought it would be a good idea to open him up to the Arduino as soon as possible. The super secret locking box will only open for those with right password or there is a hidden way to reset the passcode so that no prying little si ...

More Humane Moisture sensor

Recently I got a project from Titan industries, who were in search of something as an interactive plant pot which could bridge this gap of emotional communication, in mins this reminded me of brilliant projects done by people where the plant could could tweet and send mails and txts and on your command over the cloud, could also self water them. But all this is good only if you stay away from your home for ...

Weather Station Receiver using Arduino

The incredible popularity of home weather stations shows that it's not just farmers who are interested in the weather. Many people want to be able to track and record weather events within their local environment rather than relying on a state or national weather service that may not have adequate local details. Home weather stations typically consist of two major parts: the sensors that sit outside and mea ...

Security / Automation Sensors using Arduino

Security system sensors such as motion detectors, reed switches, pressure mats, glass-break detectors, infra-red beams, and conductive film can be very handy for all sorts of things including home automation systems, interactive art installations - and sometimes even security systems! Almost all security system sensors provide a simple switched output that changes state based on whether the sensor has been ...

Visual Navigator Making it MOBILE using Arduino

Obstacle avoiding vehicle, continue in “3D Laser Range Finder” series ( project 1, project 2). The basic idea is the same, measuring distance using red laser pointers, CCD analog camera and Arduino UNO.  Modification was made in geometry.  Two lasers were set for “far field” obstacle detection, few meters in front of vehicle on left or right side. Primary mission is to trigger left / right turn before a car ...
