It’s even complete with 3D printed enclosure and sensor elements. [Juangg] designed it to use three sensors: a pulse sensor, a breath sensor, and one to measure Galvanic Skin Response (GSR).

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

It runs on an Arduino MEGA 2560 PRO (or similar microcontroller) and supports a wide array of additional hardware including pressure transducer, water level sensor, flow meter, OLED display, and more.

While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that can measure pressures as low as 1 Pa. I was not able to find online a ...

The pressure sensor exhibits a wide detection range of 14.7 Pa–109.2 kPa, a high detection precision of 0.92‰ in full scale (FS), and an exceptional linearity ($ {R}^ { {2}} \gt 0.997$ ) in medium ...
