The humidity sensor has a maximum range of 0 to 100% RH and an accuracy of 3% at 25 ° C, as shown in
Figure 11
. We can have an error of
up to 3% RH in any adopted range.
This error is even in a wide range as the maximum (0 to 100% RH) or in a narrower range, such as 20 to 80% RH.
A serial port configuration error may occur when other software uses the same serial port. Before using it, you must terminate all
software that uses the serial port specified for TxConfig.

RETRANSMITTING THE DEW POINT
To use the
RHT
and transmit the dew point instead of relative humidity, you must follow the following steps:
•
Connect the device to the
TxConfig
interface and run the software.
•
The software will recognize the
RHT
model, read its configuration and make it available to the user.
•
In the "Options" menu, enter "Humidity Reading Type" (only available when an
RHT
model is detected) and select the "Dew Point" option. At
this point, the values of the scales will be converted to the dew point unit, ie degrees (Celsius or Fahrenheit, as selected).
•
Proceed with the configuration and send it to the device via the "Apply" button.

Dew point
If the "Humidity Reading Type" option does not appear even after the
RHT
transmitter is correctly detected, the
TxConfig
software version is
probably old and does not support this feature. In this case, download and update the latest version.
