HYTEMOD-I2C-HUMIDITY MODULE WITH
VOLTAGE OUTPUT AND I²C-BUS
Application guidelines
First of all, the operating voltage should be selected as low as
possible, in case humidity values above 80% RH are to be measured.
Because of the compact size, the electronics can get heated slightly,
which can result in a loss of measuring accuracy.
The calibration at works is done at 8 V. The specied technical data
are valid for this operating voltage. Other congurations and special
calibrations as per customer requirements are also possible.
For connection of probes in longer routes, the
I
2
C-Bus, which is used outside the device, should not be used
internally, to avoid effect of inter-connection disturbances on internal
device communication. The EMV-guidelines are to be followed; use of
shielded lines is recommended.
Due to short time interruption of operating voltage, a RESET of humi-
dity probe can be initiated. If the operating voltage is adjustable, then
the pull up resistors of I
2
C Bus must be connected to the triggering
voltage.
For simplifying your product development, a communication Board
and also an USB-I
2
C-adapter is available – please contact us !
