This LPG gas leak detector uses an Arduino Uno and MQ-5 gas sensor to detect gas levels in the air and activates a buzzer and LED to alert users when a leak is present. This is a beginner-friendly ...

Abstract: In this work, we develop a flexible capacitive pressure sensor with simple structure, low cost, wide operating range, excel repeatability and high sensitivity. The sensor greatly reduces ...

While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that can measure pressures as low as 1 Pa. I was not able to find online a ...

Abstract: In this paper, a contamination-insensitive differential capacitive pressure sensor with a sealed gap is presented. This device is made of three polysilicon layers including a stationary ...

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 ...

The hydrogel pressure sensor had a very sensitive response (gauge factor = 1.36) in the strain range from 10 to 80%, which made it possible to detect mechanical motion accurately and reliably. The ...
