| Summary: | In a humidity sensor development, the sensor testing stage is an evaluation stage
as well as a stage for observing the characteristics of the sensor being developed.
However, in the ITB laboratory, there are still deficiencies in the test method,
namely in terms of time efficiency and limitations for conducting temperature
conditioning. Therefore, a device was designed that could manipulate the humidity
and temperature of the test room according to the test requirements in less time
than the previous method. The subject matter in this document is the humidifier
subsystem, dehumidifier, and data acquisition on resistive test sensors that are part
of the overall system builder. Humidifier and dehumidifier subsystems work with a
humidity control system that uses if conditions to regulate the on and off conditions
of the subsystems. Data acquisition on the resistive test sensor is done by measuring
the output voltage value of the Wheatstone bridge circuit which converts the test
sensor resistance value into a voltage value. |
