Descriptions
The UbiBot WS4-A Data Logger is a professional temperature and humidity monitor equipped with high-precision sensors for real-time and accurate environmental tracking. With Dual-Band WiFi (2.4GHz / 5GHz), it provides stable and efficient data transmission.
The device includes a Flight Mode function that disables all wireless communication while retaining local data collection—ideal for air transport or network-restricted environments requiring high data security and compliance.
Powered by a Type-C interface and a built-in lithium battery, the WS4-A supports flexible deployment and long-term operation. Its dynamic acquisition mechanism automatically increases sampling and upload frequency when thresholds are triggered, enabling rapid and reliable anomaly alerts.
With 300,000 data points of local storage and offline resume transmission, the device continues recording even without a network connection and syncs data automatically once reconnected. The IP65-rated design provides strong protection against water and dust, ensuring stable performance in harsh environments. Multiple installation options—desktop, wall mounting, and accessory-based setups—allow easy adaptation to various scenarios.
The UbiBot WS4-A Data Logger connects effortlessly to the UbiBot IoT Cloud Platform, delivering real-time multi-sensor insights and seamless cross-device control, empowering businesses of all sizes with fast, scalable edge-to-cloud operations.

The WS4 series device has an IP65 protection rating, which effectively prevents dust ingress and resists low-pressure water jets. However, when exposed long-term to harsh outdoor environments (such as continuous rainfall, high humidity, or intense sunlight), there is still a potential risk of moisture or rainwater gradually infiltrating, which could affect the device’s long-term stability and service life.
It is recommended that for outdoor use, the device be installed in a weatherproof outdoor distribution box or other sheltered environment to enhance its reliability and durability in complex climatic conditions.

FAQ
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 when you move it to a WiFi environment. Alternatively, you can manually export the data via our PC Offline Tool or WiFi AP.
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. All your data are kept unchanged when you changed the WiFi password or even you move the device to a new location.
3. Is there any subscription fee for using the platform?
There is no need for a 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 your device takes temperature, humidity, and light sensor readings every 10 minutes.
