is done indoors to detennine the maxImum distance data
transmission between the access point and the computer. From
the test results obtained maximum delivery distance is only 69
meters. This is not in accordance with the datasheet
information which indicates the access point shipments
reached a maximum distance of 100 meters . This is because
the signal of access point is blocked by a wall so the data can
not be transmitted maximum like indicated on the datasheet.
Humidity sensor (HSM 20-G) test is done by comparing
the value of the humidity sensor readings with hygrometer
readings. To get the value of different humidity, the test is
done at different times and locations. Tests are carried out
since noon, night and morning, while test locations are indoor
and outdoor areas. The average error percentage of sensor
readings are 1.54% at sensor-l and 3.53% at sensor-2. The
test results of humidity sensor can be seen in table 2 and figure
