A research team affiliated with UNIST has unveiled a technological advancement that allows body heat to generate electricity ...

Most relative humidity sensors are resistive or capacitive sensors. It’s a fact that the resistance and capacitance of a vast majority of such sensors also depend on the surrounding temperature and a ...

This is an Arduino library for the calibrated AM2302/AM2303 digital temperature and relative humidity sensor on a DHT22 breakout PCB.

The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors.

In this study, a fully flexible inkjet-printed graphene-based capacitive humidity sensor is investigated using graphene oxide (GO) as sensing material mixed with Polyacrylic Acid, PAA. The printed ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.
