Micro-USB Cable Splitter 1. Product Overview The UbiBot Micro-USB Cable Splitter converts a single Micro-USB port into two Micro-USB female ports. It can be used with UbiBot WS1 and WS1 Pro devices. 2. External Interface Overview of WS1 and WS1 Pro WS1: The WS1 has only one Micro-USB port, so only one splitter can be connected. WS1 Pro: The WS1 Pro has two Micro-USB ports, and both ports can be connected to a splitter. 3. Instructions for Use The Micro-USB Cable Splitter offers multiple connection options when used with WS1 and WS1 Pro devices. 3.1 Using with WS1 When used with WS1, the splitter connects to the Micro-USB port. One end connects to a power adapter, and the other end connects to an external temperature sensor. The WS1 can also work without the splitter by directly connecting a temperature sensor and using two AA batteries for power. In this case, please pay attention to the battery level to avoid unexpected shutdown. (2) When a splitter is connected to Micro-USB2, one end can be connected to a power adapter, and the other end can be connected to an external temperature sensor, or to an RS485 sensor such as an air temperature & humidity sensor, soil temperature and moisture sensor, wind speed sensor, or light sensor. (3) The splitter can also connect two different types of sensors at the same time, for example, one external temperature sensor and one RS485 sensor. RS485 sensors can include air temperature & humidity, soil temperature and moisture sensor, or wind speed sensor. ⚠️ Note: The splitter cannot be used to connect two identical external sensors at the same time. For example, do not connect two temperature sensors, or two RS485 sensors simultaneously, as this may cause data errors. (4) The two Micro-USB ports on the WS1 Pro can also be used in combination with Micro-USB Cable Splitters to maximize the functionality of the device, as shown below. Alternatively, both Micro-USB ports can be used independently without a splitter. Micro-USB1 can be connected directly to a power adapter, PC Tools, or an external temperature sensor. Micro-USB2 can be connected directly to a power adapter, an external temperature sensor, or an RS485 sensor. The device can be powered either by batteries or through any of the Micro-USB ports. It is clear that using a Micro-USB Cable Splitter greatly increases the convenience and expandability of the WS1 Pro. Using a Micro-USB Cable Splitter significantly enhances the convenience and expandability of the WS1 Pro.

1. Using a Micro-USB Cable Splitter with WS1 Pro / WS1 Pro-L A Micro-USB Cable Splitter can be connected to either Micro-USB port on the WS1 Pro or WS1 Pro-L. When connected to Micro-USB 1, one end can be used for charging or connecting to PC Tools, while the other end can connect to an external temperature sensor. When connected to Micro-USB 2, the splitter can be used in two ways: one end can provide power for charging while the other connects to an external temperature sensor, an RS485 air temperature & humidity sensor, or a soil temperature & humidity sensor; alternatively, one end can connect to an external temperature sensor while the other connects to an RS485 air temperature & humidity sensor or a soil temperature and moisture sensor. 2. Using a Micro-USB Cable Splitter with WS1 Connect the Micro-USB Cable Splitter to the Micro-USB port on the WS1 device. One end of the splitter should connect to an external temperature sensor, while the other end connects to a DC power cable. This setup allows the device to use an external temperature sensor while simultaneously receiving DC power.
