Gravity: Analog Alcohol Sensor (MQ3) Category_Robot Kits/BEAM Wide operating voltage ranges and

Wide operating voltage ranges and the ability to deliver up to several hundred watts in a small form factor make these controllers suitable for many motor control applications

An app-level library helps you write control code for these low level peripherals in the same way you'd write any other Java app

The IoT Power Relay is designed to allow you to *safely* control an outlet device that operates at 3--48VDC or 12--120VAC

Gravity: Analog Alcohol Sensor (MQ3) Category_Robot Kits/BEAM Wide operating voltage ranges andThis is an Arduino Alcohol sensor. It uses a MQ3 probe which can be used in a Breathalyser. It has a high sensitivity to alcohol and less sensitivity to Petrol. The sensitivity is able to be adjusted by the potentiometer. The output is proportional to the density of gas. You can use analog reading to read the data from this sensor. To ease the difficulty of using this sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion
