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 ...

This project uses an Arduino Uno CH340G clone and a DHT11 sensor to build a compact weather station that measures temperature and humidity, calculates over ten derived environmental metrics, and ...

It’s an Arduino data logger that [Wdm006] takes along on the rides with him. When he gets back home, a Python scripts captures the data dump and graphs it.

Herein, we report a low-cost photometer developed by compactly assembling a RGB LED, a light sensor, and an Arduino microcontroller in a 3D-printed housing. To manage the RGB LED and the light sensor ...
