HCH-1000 Series Capacitive Humidity Sensors 50018326
GENERAL INFORMATION
The HCH-1000 Series is a capacitive polymer sensor designed
for relative humidity measurement. The sensor converts
humidity value into capacitance, which can be measured
electronically.
Polyimide is used as a humidity sensing material because of its
www.DataSheeint4hUe.rceonmt IC (Integrated Circuit) processing compatibility,
reduced temperature dependence and enhanced resistance
against contamination. The HCH-1000-Series is manufactured
using semiconductor technology.
SENSOR OPERATING RANGE
Although the HCH-1000 Series may not fail beyond the limits,
as shown in Figure 2, the specification only applies to
operation within the working range.
FIGURE 2: OPERATING RANGE
STANDARD CHARACTERISTICS
The sensor consists of a grid top electrode, a polyimide layer,
and a bottom electrode. The grid top electrode on the bottom
electrode provide enhanced sensitivity compared to that of a
standard structure. Figure 1 shows the typical response curve
in a humidity range of 0% RH to 100% RH.

BASIC CAPACITANCE CHARACTERISTICS
Capacitance is measured by applying 1 Vrms at 20 kHz at
25 °C. The sensor characteristic is determined by the following
formula:
FIGURE 3: BASIC CAPACITANCE (At 25 °C, 1 VRMS, 20 kHz)
CC(%RH) = CS at 55%RH + S x[(%RH(CM) - %RH(CS)]pF
Where,

RH)
Figure 3 shows the typical characteristic curve. The average
increase in capacitance value within the working range of
10% RH to 95% RH is typically 56 pF.
HYSTERISIS CHARACTERISTICS
Figure 4 shows the hysteresis curve. The hysterisis formula is:
HysteresisValue = C(20%RH 95%RH ) C(95%RH 20%RH )
Where,

The hysteresis value is measured under 1 pF. The hysteresis
of measured samples indicates between ±3% RH at each
humidity point.
