ANALOG HUMIDITY SENSOR BOARD

This breakout board is equipped with a hygrometric sensor, thus

it lends itself to detect the moisture found in the environment it is

placed in. It operates at a very low voltage (it correctly operates at

up to 5.5 Vcc) and typically absorbs 200 microamperes: it is thus

ideal even in applications that are battery powered, and in which a

minimal absorption is required.

The HIH-5030-001 sensor has the great virtue of supplying an

analog output signal, consisting in a DC voltage that varies in an

almost linear manner, as the relative humidity (RH) varies; thus it

may be interfaced both to analog circuits that check the air ow of

a dehumidier installation, and it may be read by an A/D converter

or by a microcontroller’s input that is supplied with an analog/digital

converter.

The device’s sensor component is of the capacitive kind, and it is

composed of thermosetting polymers that have been cut with a la-

ser. The signal’s conditioning circuitry, integrated on a chip, is found in

the integrated circuit. The multilayer construction of the sensitive ele-

ment provides an excellent resistance to the greatest part of the risks

coming from applications such as, for example, condensation, dust,

lth, oils and common chemical products found in the measurement

environment.

The measurement accuracy is ÷3%, given that the relative humidity is between 11% and 89%; the response time

to the humidity variations is of about 5 seconds. The variation curve for the device’s output voltage, as a function of

the relative humidity (having a 3.3 V power supply and an environmental temperature of 25° C) is shown in Fig. 1.

The component’s output is an high impedance one, and may pilot circuits having an impedance of no less than

65 kohms; otherwise the voltage supplied as a function of the humidity may not react to the curve shown in Fig.

1, but will vary in a different manner. In addition to the A/D converter, the device’s output may be connected to a

microampere meter having a pointer, or to an opportunely calibrated voltmeter, so to create a veritable hygrom-

eter, from which to obtain a direct indication of the relative humidity.
