Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...

This paper analyzes the performance of mosaic nonimaging passive infrared (PIR) sensors fabricated by the CMOS-SOI-MEMS technology. The elementary sensor, forming a subpixel, is a thermally isolated ...

In this paper, a hand gesture detection and classification system using two differential Pyro-electric Infrared (PIR) sensors and a camera is introduced. Motion presence is investigated in the area of ...

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 ...

The Arduino code is located in the arduino-code folder. The code still lacks the ability to measure pressure and it is a mess (I merged several online projects). It measures the pressure in mV. As ...
