This is a small project to get you started with the electric imp and a Thermistor so you can see how you can get temperature readings updating live on a web site. This instruct able will address both the hardware and the web site along with all the parts in between. I’ve tried to keep …
Description The MAX31850/MAX31851 cold-junction compensated, 1-Wire® thermocouple-to-digital converters perform cold-junction compensation and digitize the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The converters resolve temperatures to 0.25°C, allow readings as high as +1768°C and as low as -270°C, and exhibit thermocouple accuracy of 8 LSBs (2°C) for temperatures ranging from …
This article looks at the latest touchscreen sensor technologies and the wide range of interfaces that the different technologies use. It also evaluates the different approaches for interfacing such sensors for human interfaces from three, four and five wire to USB, covering sensors and interfaces from Atmel, 3M, IR Touch Systems, and NKK Switches. Resistive …

At this week’s International Image Sensor Workshop (IISW 2013, Snowbird, Utah, June 12-16 2013), imec and Holst Centre presented a large-area fully-organic photo detector array fabricated on a flexible substrate. The imager is sensitive in the wavelength range suitable for x-ray imaging applications. Because of their very high absorption coefficient, organic semiconductors allow extremely thin …
The heart rate, also referred to as pulse rate, has been recognized as a vital sign since the beginning of medicine, and it is directly related to a person’s cadiovascular health. Today, we are going to make a PC-based heart rate monitor system using an Arduino board and Easy Pulse V1.1 sensor. Easy Pulse is …
