Real-Time Data Display with a 4.4'' LCD Screen

The 4.4'' LCD screen provides instant access to real-time data, including temperature, humidity, light levels, and external sensors—all at a glance.

Supports Connection to Multiple External Probes

The WS1 Pro-L features two on-board USB ports. The lower port supports RS485 interface probes, including the TH30S-B, soil sensor, and PT-100, with a limit of one of each type connected at a time. Additionally, you can connect two temperature probes simultaneously using a USB splitter.

High Accuracy Measurement

Experience exceptional precision with our advanced high-accuracy sensor, providing temperature measurements within ±0. 2°C from -20°C to 60°C, humidity accuracy within ±2% RH (10% to 90% RH), and ambient light accuracy within ±10% (0.01 to 157k lux).

Never Miss a Data Point, Even Offline

The WS1 Pro-L boasts built-in memory that can store up to 50,000 data points, enabling continuous recording even when offline. When the device reconnects, it automatically synchronizes all offline data to the UbiBot big data platform, ensuring no data is lost.
