Arduino Infrared thermometer

educ8s.tv has posted another great video tutorial on building an Arduino infrared thermometer using the MLX90614 Infrared temperature sensor, which uses the standard I2C protocol to communicate with the Arduino. The measured temperature is displayed on a Nokia 5110 LCD display shield. The device can measure the temperature of an object without any physical contact and with just facing the sensor toward it from a small distance. It can measure temperatures from -70 degrees Celsius to 380 degrees with an of about 0.5 degree at room temperature.

An open source chocometer to measure blood glucose level using IR light

Posted on by 2 comments
marcelclaro’s entry to HAD Prize 2015 is an open source Chocometer that can measure the glucose level in blood by shining an infrared light source.

Diabetes mellitus is a global problem, in 2013, 382 million people have diabetes worldwide, most with more than 45 years, and global economic cost in 2014 was estimated to be $612 billion USD.The future projections are not encouraging.All forms of diabetes increase the risk of long-term complications (cardiovascular disease, blindness, chronic kidney desease, etc.), however, the complications of diabetes are far less common and less severe in people who have well-managed blood sugar levels.

Today, the diary glucose level check can be done at home, nervertheless, its need a little drop of blood and a chemical reaction strip. So, this check becomes painful and expensive (each strip could cost 0.33 USD). These drawbacks decrease the patient adhesion to treatment.

I propose a glucose meter design based on light absorbance of glucose that already been extensively studied and sucessful applied in laboratory scale.
