You can add a Sensor from the Edit page in a few clicks.
First click the edit button above your Thiamis name, on the Monitor page.
Then from the Edit page, simply click the "+ Add Sensor" button on the right side of the scree, and fill out the sensor form. Simply choose the name of the manufacturer (or the model name) of the Sensor from the menu, select the Com Port the sensor is connected to, and confirm the Com Type. Click save on the bottom right to save your sensor settings.
For many sensors, you only need to chose the manufacturer name and Environet will automatically recognize the model once it's connected. For example, just choose DustTrak and it'll update to a DustTrak 8533 in minutes.
