The project's goal is to detect the presence and concentration of hazardous gases and vapours, such as toxic or explosive gases. If the gas sensor detects gas in a harmful range, the buzzer sounds, ...

The task of our LCD panel in this project is to provide visual information to the user. While the system is not active, it shows us the value from the sensor, and when the system is activated, it ...

We have used a LPG gas sensor module to detect LPG Gas. When LPG gas leakage occurs, it gives a HIGH pulse on its DO pin and arduino continuously reads its DO pin. When Arduino gets a HIGH pulse from ...

Working of LDR controlled LED using Arduino As per the circuit diagram, we have made a voltage divider circuit using LDR and 100k resistor. The voltage divider output is feed to the analog pin of the ...

Dark sensor Light and dark detection using an LDR For this project, let’s stick to the LDR sensor module so we can select the light or dark detection by placing jumpers. We’ll be using this module to ...

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 gas sensors ...
