This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors. It provides a general software solution, without requiring any additional hardware, to implement the ...

However, the accuracy and reliability of the colorimetric gas sensors are threatened by the humidity interference in different application scenarios. Though substantial progress has been made toward ...

Abstract: This paper reports an ultra-low power cantilever switch array of temperature and humidity sensors with direct digital output. The sensors are designed to measure a temperature range of ...

An Arduino project to log GPS data to a MicroSD using the tiny XIAO ESP32-C3. The components are small and light enough to fit around a cat collar! Now we know where the cat runs around at night :-) ...

The sensors also build in rainfall data and other scientific measurements to assist understanding of its effects on increased bacteria levels. The Shrewsbury project replicates the work the ...

Abstract: This paper presents a novel inkjet-printed humidity sensor tag for passive radio-frequency identification (RFID) systems operating at ultrahigh frequencies (UHFs). During recent years, ...
