Arduino Uno is used for acquiring data from both electronic and optical sensors simultaneously. Both the electronic and optical sensors are fitted inside the same PVC mask, and their responses are ...

An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...

The SGP30 is a digital multi-pixel gas sensor designed foreasy integration into air purifier, demand-controlledventilation, and IoT applications. Sensirion’s CMOSens®technology offers a complete ...

It comes with a number of improvements compared to the first generation model, featuring upgraded sensors, hand and eye tracking systems, and a photoplethysmography (PPG) sensor just like the Apple ...

This paper proposes a low-noise AFE based on a capacitive transimpedance amplifier (CTIA) for wearable PPG sensors. By separating noise from the PPG signal, the proposed AFE applies chopping technique ...
