PPG570 ATM to Medium Vacuum Gauge + ATM Switch The new INFICON Pirani Piezo combination gauge (PPG570) is based on the most advanced MEMS (Microelctromechanical Systems) sensor technology available, which is also used in our PPG550 "ATM to Medium Vacuum" Gauge. What differe...
A PPG signal collected with a precise sensor in a controlled environment is reliable. However, if the PPG signal is unstable, an additional biometric signal can improve the result (Spachos et al., 2011). ECG can be recorded simultaneously with PPG and provide a multi-fact biometric system. ...
The dataset in question was collected by the digital systems research team at the University of Science and Technology in Mazandaran, Behshahr, Iran (MUST)32. It contains 67 raw PPG signals, sampled at a frequency of 2175 Hz. Each entry in the dataset is accompanied by labels for age, gend...
HealthyPi 5 is an open-source sensor platform for biosignal acquisition based on Raspberry Pi RP2040 microcontroller and ESP32-C3 WiFi & BLE module used to capture vitals such as electrocardiogram (ECG), respiration, photoplethysmography (PPG), oxygen saturation (SpO), and body-temperature data. ...
