| Summary: | The paper presents the working principle of the alcohol sensor, which is
connected to the on/off switch on the chainsaw. The alcohol sensor switches
off the chainsaw via the transmitter and receiver, if it detects that the
worker is under the influence of alcohol. The connection between the
transmitter and the receiver is remote, via radio waves. The alcohol sensor
contains a mesh that heats up due to 5V voltage impact and reacts to alcohol
vapors. This reaction is an incentive to send a signal from the transmitter
to the receiver. Blockage - switching off of the chainsaw occurs when a short
circuit is made between the power supply and ground. This short circuit also
occurs when the chainsaw stop switch is manually switched to the "0" state.
By using an alcohol sensor, a transmitter and a receiver, the "0" state on
the switch is achieved wirelessly. The receiver (relay) makes a short circuit
instead of a switch, which causes the chainsaw to stop working. This way of
stopping the chainsaw indirectly protects the worker from injuries due to
alcohol consumption. |
