Description The MAX44007 ambient light sensor features an I²C digital output that is ideal for a number of portable applications such as smartphones, notebooks, and industrial sensors. At less than 1µA operating current, it is the lowest power ambient light sensor in the industry and features an ultra-wide 22-bit dynamic range from 0.025 lux to […]

Description Plessey Semiconductors Electric Potential Integrated Circuit (EPIC) product line targets a range of applications. The PS25451 is an ultra high impedance noncontact solid state electric potential sensor. It can be used to detect field disturbance due to the movement of a near-by object. This functionality can be employed in a range of applications including security motion sensors and non-contact electric switches for […]

Wear is an affordable, attractive, lightweight wearable assistive directional microphone designed to improve quality of hearing. Wear is an assistive device designed to improve quality of life for people with hearing loss.   Wear is a high fidelity directional analog microphone that is significantly lower in price than existing hearing aids.  This microphone can be used with any […]

Introduction This is the second in a series of tutorials examining various uses of the Arduino Yún. In this article we’ll examine how your Arduino Yún can send data that it captures from the analogue and digital inputs and a real-time clock IC to an online Google Docs spreadsheet. Doing so gives you a neat and inexpensive […]

This device was created for a final project for a class by a group of students at Indiana University. As sport fans, we thought it would be really useful to create a tool that would measure distance between two points. This could be used for many different sports, but we focused on golf. A handheld […]
