Ubibot WS1 Pro – Universaldatenlogger

Wi-Fi and mobile data connection for easy access worldwide

The UbiBot ® WS1 Pro is a state-of-the-art environmental monitoring system that uses the latest IoT technologies. The data from the measuring sensors are recorded and saved in real time. The device saves the data in the IoT cloud via WLAN or mobile radio, thus allowing worldwide access. All your data is automatically synchronized with the UbiBot® IoT platform and you can easily access your device via our app or a browser.

*Depends on specific models purchased.

Super Clear LCD Screen

The WS1 Pro has a bright and clear 4.4-inch LCD screen. This shows the current measured values and provides you with all alarms and notifications in real time.


Device Setting: the minimum device sync interval (upload) is 1 minute, and minimum sensing interval is 1 minute (Temperature, Humidity, Light, External Probe and Battery Voltage).
Alarm types: Supports APP push notifications, email, SMS text, voice notifications by phone call and audible notifications. Alerts can be set to numeric sensor values and network status (e.g. when the connection is lost or the batteries are low). All warnings are sent from the UbiBot Cloud.

① The sensor precision might fluctuate slightly in actual usage because of enviroment condition, deployed position, etc. See user guide for detailed parameters.
② The specified battery life has been tested with VARTA industrial batteries under stable signal conditions with standard settings for synchronization and scanning.

* Depending on the specific model purchased.

⚠️The device is not waterproof. For outdoor or indoor use with a constant humidity of 90% or more, use the water-proof protective cover and use an external sensor.

Probe Connection Diagram

The WS1 Pro device has two integrated USB ports, the lower port of which supports temperature and humidity sensors with an RS485 interface, such as the TH30S-B, the USB floor sensor or the PT-100 for industrial applications. Only one sensor of each type can be connected. Two DS18B20 temperature sensors can be connected simultaneously via a USB splitter.

Compare UbiBot® smart sensor devices

UbiBot® currently has four versions of the intelligent data logger for temperature and humidity monitoring. All are based on the same underlying IoT technology and are equipped with Swiss quality sensors. Each device type is characterized by specific functions that are specially tailored to the different requirements of the user.
