- UbiBot WS1 is not waterproof. The optimal operational environment is 10% to 90% relative humidity (RH). Long-term exposure to a highly humid environment, over 90% RH, may cause damage to the device.

- If used for a freezer/fridge, please connect a DS18B20 external temperature probe, and put WS1 outside of the freezer/fridge.

- WS1 can work with a 2.4GHz WiFi network or 2.4/5 GHz mixed network. 5GHz WiFi is not supported.

- UbiBot WS1 supports 1 x DS18B20 Temperature Probe.

- With a Micro-USB Cable Splitter, WS1 can connect 1 x DS18B20 Temperature Probe and external power supply at the same time.

- If the UbiBot device is used in continuously high humidity (over 90% RH), we suggest using the UbiBot water-resistant case and connecting DS18B20 external probes.

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.

Data Sheet

1. Does the device collect data when the network is unavailable?

Yes. The device continues to monitor the environment even when no network is available. It stores the data in its on-device memory and will sync it to the UbiBot IoT Platform once the connection to the WiFI network is established. Alternatively, you can manually export the data via our PC Offline Tool or Web Console.

2. How to reset the device when my WiFi router password is changed?

Repeat the device setup steps and follow the on-screen instructions. Note: you need to type in the new WiFi password. When you change the WiFi password, or even when you move the device to a new location, all the data collected by the device will remain unchanged.

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

The WS1 device supports one DS18B20 temperature probe. When you need both USB power supply and external probe connection at the same time, you can use the Micro USB Splitter Cable Adapter (One Male to Two Female).

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

No subscription is needed to use the UbiBot Platform.

Each device comes with the free plan on UbiBot platform that offers 200 MB storage and 1 GB outbound traffic. The 200 MB storage is for lifetime and 1 GB of outbound traffic is available monthly to each device. Note that any unused balance of the outbound traffic will not roll over to the next month. For example, if you have 500 MB of outbound traffic unused this month, you will still have 1 GB available for a specific device the next month, you won’t have 1.5 GB. The free 200 MB storage is enough to store over 2 years’ worth of data in case your device takes temperature, humidity and light sensor readings every 10 minutes.

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

5. Can the device be powered by USB power supply?

Yes. The device supports both AA batteries and Micro USB power (5V2A). The device can preferentially use USB power if both USB and batteries are available. In this case, you can insert 4 AA batteries as a backup for the power supply in case the socket power is cut. Rechargeable batteries are also supported, but please note the device won’t charge them when USB supply is plugged in.

6. Why didn’t I receive the verification email for registration?

The email is probably blocked by your email server. Please check your spam or junk mail first. If you still can’t find the verification email, please send your registration email address to so we can check if there are some issues on our end.
