- Outputs 5 elements with different measurement ranges as analog voltage or current (standard) - Outputs an additional 12 elements with different measurement ranges as analog voltage or current (via optional extended analog output) - Five types of communication interfaces: RS232C, RS422, RS485 Modbus-RTU, RS485 multi-drop, and AoXnd mode for extended analog output - Averaging interval for all output values can be arbitrarily set from 1 to 60 seconds or 1 to 60 minutes - Achieves measurement accuracy of ±1% for wind direction and speed measurements through raw data processing and evaluation algorithms - 50Hz data output via high-speed digital sampling mode, or high-speed analog data sampling at 5Hz and 20Hz - Orientation adjustment to magnetic north using an integrated compass - No moving parts, significantly reducing maintenance and service costs - Robust and reliable structure suitable for long-term use in harsh environmental conditions - Heater function option: The built-in heater function prevents icing and snow accumulation on the ultrasonic sensor, ensuring high-precision measurements - Optional full-duplex 4-wire output for RS422 communication

■ Equipped with 4 analog inputs, 2 contact inputs, RS485 Modbus-RTU, and SDI-12 digital inputs, allowing for a wide variety of sensor connections. ■ Built-in LTE module for data transmission via email and FTP, and data upload to HTTP servers such as Senseka Cloud (free). ■ Alarm contact output x2, alarm notifications via email and SMS. ■ Powered by external DC power supply or solar panel, with built-in battery life of several weeks. ■ Time synchronization with HTTP or NTP reference servers using the built-in clock. It enables remote monitoring and alarms for various physical quantities such as temperature, humidity, atmospheric pressure, solar radiation, rainfall, wind direction and speed, and water level for disaster prevention applications like general weather and flood monitoring. Upon request, an M12 connector input for a combined probe of relative humidity and temperature (NTC sensor) or a dedicated temperature (NTC sensor) probe can also be supplied. With 4G (LTE) data communication, there is no need to remove data storage devices or download measurement data to a PC after going to the site. Measurement data can be sent via email, FTP, or uploaded to an HTTP server (e.g., to Senseka Co. (formerly Delta Ohm) at www.deltaohm.cloud).
