ENVIRONMENTAL TEST SYSTEM
Figure 5 depicts environmental testing. The devices are
characterized at 25 °C [77 °F] between 20% RH and 95% RH.
The meter is set to measure capacitance at 1 V and 20 kHz.
FIGURE 5: ENVIRONMENTAL TEST SYSTEM DIAGRAM
For a precise measurement, a hygrometer is compared with
the humidity of the temperature-humidity chamber.
The data output indicates the effect of sensor characterization
before/after environmental tests.
