In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Light aircraft often use a heading indicator as a way to know where they’re going. Retired instrumentation engineer [Don Welch] recreated a heading indicator of his own, using cheap ...

Tired of your old Arcade games which all looks and works in the same way? Want to create a quick fun game which you can enjoy with your friends and family without using any thought? You are at the ...

Abstract: The chemiluminescent signal in lab-on-a-chip (LOC) is generally weak and also has a short lifetime, hence, a sensitive and fast detector is required for detection. Aiming for acquisition of ...

This module is based on the I2C light-to-digital converter TSL2561 to transform light intensity to a digital signal. Different from traditional analog light sensor, as Grove - Light Sensor, this ...

Abstract: Photoplethysmography (PPG) is a key technology allowing non-invasive monitoring of vital indicators such as heart rate (HR) and oxygen saturation (SpO 2). Today, the total PPG sensor power ...

(1) Prolonged exposure for 60 hours at humidity > 80% can lead to a temporary drift of the signal +3%. Sensor slowly returns to the calibrated state at normal operating conditions. (2) High frequency ...
