In past tutorials, we have covered temperature, color, time, direction, but never distance or proximity. I think I strayed away from this because most of the lower cost proximity sensors are pretty drop-dead-simple to use and thought it might not be that useful. But the time has come, I’m writing about some distance/proximity sensors. While […]
Are we getting close? Proximity Sensors + Arduino Continue Reading
PORTLAND, Ore. — Complementary metal oxide semiconductor (CMOS) imaging chips are becoming the industry’s leader in advanced process technology — instead of the traditional leaders (processors and memory) — thanks to strong demand for CMOS imaging chips in everything from smartphones to tablets to medical equipment and automobiles. Apparently, now the innovation surpasses Moore’s Law,
Note: When referring to Arduino below, this works in the same way on the emonTx which is arduino-based. The DS18B20 is a small thermometer with a built in 12bit ADC; it can be easily connected to Arduino digital input. The sensor communicates over a one-wire bus and requires little in the way of additional components.

Proximity sensors working on an induction principle are able to detect ferrous and non-ferrous metals very reliably. For those of you, who already work in this field, there´s everything clear for you probably and you know well, that induction sensors are literally one of the keystones for an industrial automation. For all of you, who´re
Induction sensors don’t need a touch, they’re satisfied by proximity Continue Reading
John has been working to recover components from old power supplies and available trash electronics, in order to build controllers to power stepper motors and other mechanisms for the FabLab. Intro The Arduino microcontroller board is able to supply a current of 40mA from its output connections. These digital outputs are fixed at 5V “ON”
Our sensor technology is ideally suited for any project requiring very compact, low power, high performance distance measurement sensors, such as drones, robots, or unmanned vehicles. PulsedLight’s novel signal processing technology enables us to offer a low-cost optical distance measurement solution with performance comparable to systems costing hundreds of dollars. “PulsedLight takes distance range finding
Scientists have come up with a way of creating sensors which could allow machines to smell more accurately than humans. Every odour has its own specific pattern which our noses are able to identify. Using a combination of proteins coupled to transistors, for the first time machines are able to differentiate smells that are mirror

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

Overview: This instructable will construct a series of custom sensor modules and an Arduino shield. Such modules are available from many different sources, but fans of the Instructables website would probably find satisfaction in making their own. Each module will be a set size of 1.5cm by 2.5cm and employ a three pin connector of
