⚠️The UbiBot WS1 Pro is not waterproof. The optimal operating environment is 10% to 90% rH.
For outdoor or indoor use with a constant humidity of 90% or more, we recommend using the UbiBot waterproof protective cover and and the Connection of external sensors.

Probe Connection Diagram

The WS1 Pro device has two integrated USB ports, the lower port of which supports temperature and humidity sensors with an RS485 interface, such as the TH30S-B, the USB floor sensor or the PT-100 for industrial applications. Only one sensor of each type can be connected. Two DS18B20 temperature sensors can be connected simultaneously via a USB splitter.
