Abstract: The paper
presents a device made within the Automation Laboratory
of the Wood Industry Faculty. The device employs
the SHT11 digital output dual sensor for temperature
and relative humidity. The sensor is used with
certain computerized wood drying installations
or with air-conditioning installations. The same
sensor can be successfully employed to lead the
wood drying process in small sized installations
for experimental determinations. As for the latter,
the Automation Laboratory of the Wood Industry
Faculty realized and experimented different circuit
diagrams which connect the sensor to a PC compatible
computer. The final connection variant makes use
of a microcontroller with alpha-numeric display
and RS 232 interface of communication with a computer
in order to record the experimental data.
Key words: sensor, relative humidity
and temperature, microcontroller, computer, drying
installation.
