Ubibot insists on researching and developing self-owned patent products, including the external probes that match our sensing devices.

There are three types of probes that can match with the WS1 and WS1 Pro device. Here are the instructions of how to use them.

Using WS1 device:

This device supports DS18B20 probe. As it only has one USB port, only one probe can be connected. When using USB power at the same time, one USB splitter is needed. Connect the splitter to the device USB port, one female port is for power and the other is for data transmission.

Using WS1 Pro device:

This device supports DS18B20, TH30s-B, and soil temperature and humidity probe.

It has two USB ports, of which the lower one is embedded with RS485 interface. Except the DS18B20 probe, the others both need to be connected to this lower USB port. Our feature probes, such as CO2 probe, wind speed probe and PT100 extreme temperature probe also require connection to this interface. While, you can use DS18B20 on either of the USB port. When you need to power the device via Micro USB and you want to connect more than two probes at the same time, please remember, the ends of the splitter must be connected with one power supply and one probe, or one DS18B20 and one RS485 probe. Two same probes are not supported.
