Introduction
Relative humidity (RH) sensor HDS300 is specially designed for optimal work with devices from NetControl series concerning supply, range of measurement and accuracy.
It has a keyed connector for direct attachment to NetControl devices.
IMPORTANT! This sensor is connected to NetControl trough the same connector on back panel used for temperature sensor TDS300. To allow visualisation of humidity in % you will also have to change the settings of NetControl device telling it that "Humidity HDS300" sensor is used (this option is avaibale in 'I/O settings' web menu from firmware version 3.4). Please, give attention to the fact that any change in measurment mode must be reflected in cloud platform via icon (
); thus synchronizing the channel type between device and platform.
This sensor can be used with other devices that have analog input for range 0..3.3VDC.
