UbiBot WS1 Pro has two Micro USB ports for connecting external probes or USB power supply.

- Each Micro USB port supports 1 x DS18B20 temperature probe.

- The lower Micro USB port also supports one following RS485 probes:

TH30S-B Air Temperature and Humidity Probe
Soil Temperature and Moisture Sensor
PT 100 Industrial-grade Temperature Probe
Wind Speed Sensor

- Splitters may be needed when you connect multiple external probes and external USB power supply at the same time.


- Only one RS485 probe can be connected at a time, it can't support more than one RS485 probes at a time.

Real-time and history data

The UbiBot Platform is a cloud-based IoT platform where all measured data is uploaded and stored. UbiBot App and Web Console allow you to view current data as well as historical data in graphs. The adjustable Y-axis scale allows you to view any tiny fluctuations in the curve.

Customizable alerts and bulk operation

Setting and receiving alerts on your devices helps you to get notified of the conditions timely. When you have many devices to manage, it’s time-consuming to set each alert rule one by one. Therefore, we’ve developed a bulk operation module with which you can set the same rule for many devices at a time.

Free data export

On UbiBot Platform, you can download the history data in CSV or PDF format. The CSV file only contains raw data, while the PDF file is a summarized report with average, maximum and minimum value within the chosen period. The PDF file is much easier to read and archive.

Device sharing and bulk operation

For business users, centralized control over multiple devices is available, with no limit on the number of devices in one account. Also available are bulk operations that apply to sensor settings, alerts, and remote control routines. Devices can be shared with other people, which allows for distributed management by different colleagues.

Intelligent automation in UbiBot platform

UbiBot is committed to building intelligent industrial and home ecosystems. By integrating temperature and humidity sensors and the smart plug SP1 in one system, automated operation is achieved through data linkage. For example, fans can be switched on when the temperature rises to 30 °C.

Data forwarding

UbiBot is an open platform that provides cloud-based services while supporting customers to use their own storage servers. With the data forwarding service, you can forward the data collected by your device to your own private URL to protect privacy.

Location tracking and logging

UbiBot GS1-PL4G1RS is embedded with GNSS (Global navigation satellite system) for positioning. Through mobile data communication, real-time location information is transmitted to the platform and recorded. The UbiBot platform integrates this data, plots it into a trajectory map, and presents it.

Platform-based calibration

UbiBot platform supports data calibration both on the platform level as well as the device level. One-step calibration, instant display, no impact on historical data.

SIM card management

When using UbiBot Global SIM to transfer data, you can manage it by yourself. Unlike other SIM cards with a standard monthly fee and traffic amount, our SIM supports many types of plans. Choose the one that suits you now, and change to another next time. No arrearage and no extra charge.

3. What kind of probe can be connected with the device?

The WS1 Pro supports 2 x DS18B20 temperature probe. The embedded RS485 interface allows soil temperature & humidity probe as well as environment temperature & humidity probe to be connected.

4. Is there any subscription fee for using the platform?

There is no need of subscription to use the UbiBot Platform.

Each device comes with the free plan on UbiBot platform that offers 200MB storage and 1GB outbound traffic. The 200MB storage is for lifetime and 1GB of outbound traffic is rotated monthly for each device. But any balance of the outbound traffic will not roll over to the next month. For example, if you have 500 MB outbound traffic unused this month, you still have 1 GB next month.
The free 200MB storage is enough to store over 2 years amount of data in case of your device takes temperature, humidity and light sensor readings every 10 minutes.

You can also pay for larger amount of storage and outbound traffic. Please go to the “Pricing” page to see details.

5. How long will the batteries last?

With the default sync interval of 30 minutes, the device has a battery life of up to 4-6 months using 4 AA alkaline batteries. According to our test, the VARTA industrial batteries are recommended for better performance.
