Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...

Here is a gas leak detector circuit that detects the leakage of LPG gas and alerts the user through audio-visual indications. The circuit operates off a 9V PP3 battery. Zener diode ZD1 is used to ...

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...
