Sensor – Transducer – Detector Project Ideas

Arduino Weather Station Part2

So my last project was a Arduino wind chill machine. http://www.instructables.com/id/Arduino-Wind-Chill-Machine/ Naturally, this Lazy Old Geek wanted to add a weather vane (wind direction) to my weather station. Who cares, you may ask? Well, I am a Geek. Actually, wind direction has some importance. Here in the high desert, the winds are usually from the …

Arduino Fixed-point Vehicle Proximity Detector

This is the high-tech version of hanging a tennis ball from the ceiling from a piece of string.  Of course, if you have two different types of vehicles, that tennis ball isn’t going to land in the same place on both of them.  This project can prevent hundreds of dollars in dry-wall repair and bicycle …

The CoaTracker using Arduino

Has this ever happened to you? You wake up in the morning and realize that you’re terribly late for work/class/your weekly pedicure/whatever. You throw on a t-shirt and flip flops, sprint around your warm, heated house grabbing your belongings, and race out the door…where you suddenly find yourself surrounded by a cold, biting wind encompassing …

ORP / pH / Temperature Data Logger

As a Water Quality professional working in the drinking water field, I know how important it is to accurately monitor the disinfectant levels in the drinking water that gets served to the public.  Usually, that means taking weekly grab samples in the distribution system and measuring free chlorine or total chlorine residual via a DPD …

Arduino Frequency Detection

As a follow up to the Arduino Audio Input tutorial that I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino’s analog input and determines the frequency.  The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes.  I’ve also turned the LED attached to pin …

Arduino Powered, Sensor Controlled Fading LED Light Strips

I recently had my kitchen updated and knew that lighting would ‘lift’ the look of the cupboards. I went for ‘True Handless’ so I have a gap under the work surface, as well as a kickboard, under cupboard and on the top of the cupboards available and wanted to light them up. After looking around …
