Prototype IV

The schematic picture uploaded is a vague representation of what the basic Prototype IV would look like; due to imperfect information and lack of “official” components, two generic motors are used to represent the fan and heating element/pump, respectively.

Featured are the two dummy motors (large, white rectangles), gas sensor (blue rectangle with circle, Methane, Butane, LPG and Smoke Gas Sensor - MQ-2), and a bluetooth component for wireless communication (green rectangle, HC - 05 Bluetooth Serial Module).
