The MQ-5 Combustible Gas Sensor can detect LPG, H2 ... The MQ-5 Sensor is popular among beginners since it detects combustible gases in most Arduino projects. Likewise, these are low-cost, easy-to-use ...

AOUT is the Analog output pin of the board that will give us an analog signal which will vary between vcc and ground based on the gas level detected In most Arduino projects, the MQ-2 sensor is used ...

This Arduino project is used for gas leakage detection by a gas sensor which senses the hydrogen concentration in the air. This sensor can detect hydrogen gas concentrations anywhere from 100 -10000 ...

Fig.5. Circuit with relay driver ULN2003 and relay In this proposed project, we have interfaced Arduino Uno with MQ2/MQ6 sensors, SIM900A GSM module, servo motor, buzzer, and LED. The interfacing is ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...
