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
11.
