The MQ-3 Alcohol Sensor Module features four pins, two of which are for VCC and GND. The other two may simultaneously output analog and digital data, much like the other basic sensor modules. We're ...

Creating an alcohol sensing engine lock system with GPS using Arduino involves integrating an alcohol sensor, GPS module, and a relay to control the engine. Hardware Components: Arduino Board (e.g., ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...
