Health sensor
The e-Health sensor Shield enables Arduino and Raspberry Pi designers  to conduct biometric and medical applications where body monitoring is required implementing nine unique sensors such as Pulse, Oxygen from the blood (SPO2), airflow (breathing), body temperature, electrocardiogram (ECG),glucometer, Galvanic skin response (GSR sweating), blood Pressure (sphygmomanometer) and patient movemnt (accelerometer).

Temperature And Humidity Project

Here is a cool project that we found on Hackalog.

As you all know there are many useful applications of temperature and relative humidity measurements sensors. They are readily that are available on the market consisting of both temperature and humidity sensors, signal conditioning, Analog to Digital Conversions (ADC), calibration and communication interface built in single module packages.

If you need a temperature sensor but don’t have one at hand, here’s an easy way to create one, using a .. diode ! All what you have to do is to bias the diode with a current around 1 mA, and to measure it’s forward voltage drop.

The forward voltage of a silicon diode varies with about -2 mV / °C. So, basically the diode itself can be used as a temperature sensor. In order to have a good precision, you should perform a calibration by measuring the output voltage at a known temperature. Continue reading →
