74HC155 (Dual 2-to-4-line Decoders/demultiplexers) 74HC191 The lens used here is

The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor)

Sliding case for easy access

Alcohol Sensor(MQ3) module is useful for gas leakage detection (in home and industry)

74HC595N using serial information then gathers or outputs information in a parallel (multi-pin) format

This MCU board also includes 4 UARTs (hardware serial ports)
