The Elektor STM32 Nucleo Starter Kit is the perfect entry point into the world of the widely popular STM32 microcontroller line

Alcohol Gas Sensor - MQ-3 $100-$250 This unit is MODBUS capableThis alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0 3. 3V ADC. This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance.
