Variety of applications

MAWS110 provides quality controlled data in different applications in the areas of meteorology and hydrology. It is especially designed for unmanned operations at remote sites requiring high reliability and low power consumption with expandability. MAWS110 uses a field-proven and high accuracy Vaisala data logger technology with advanced software. Each system provides the most economical and optimized product for your application.

  • Compact, robust and easy to- use automatic weather station for meteorological and hydrological applications
  • Easy and economical to install, maintain and upgrade
  • Field-proven reliability and accuracy in harsh environments
  • Low power consumption for extended remote operations
  • Telemetry options include satellite telemetry in addition to landline, wireless, and built-in TCP/IP connectivity
  • Extensive calculation and data logging capacity
  • Low Total-Life-Cycle Cost

Ease of use and maintenance

The system architecture is specially designed to support a broad range of analog and serial sensors. In MAWS110 all sensors and telemetry devices are connected to the system using high-quality polyurethane cables with IP68 connectors allowing quick and trouble-free installation. Sensor measurements, statistical calculations, data logging and data transmissions are performed according to a user-configured setup made with the user-friendly Vaisala Setup Software Lizard. All LRU modules inside the enclosure are mounted on DIN rails or replaceable units.

Field-proven reliability

MAWS110 enclosures feature IP66 (NEMA4X) protection. All the inputs have transient protection and all mains power and RF inputs are surge protected.

Power supply options

MAWS110 has low power consumption - the average power consumption is only 10 mA. In many cases a solar panel with backup batteries up to 18 Ah is enough for powering a basic MAWS110 system. A mains (AC) power supply is optional to power extended systems with frequently sending (powered) telemetry devices.

Advanced telemetry

The basic system provides interfaces with almost any type of telemetry, terminal, displays as well as smart sensors. With optional plug-in modules the number of serial ports can be enhanced from 2 up to 8 ports, enabling multiple RS-232, RS-485 and SDI-12 connections. MAWS110 can be connected directly to a LAN network using Ethernet Communication Module DSE101 offering a 10/100Base-T Ethernet. Other options for telemetry include various wireless, landline, and satellite devices.


MAWS110 is expandable with, e.g., the Vaisala Sensor Multiplexer QMU101 offering additional 10 differential analog channels. The Vaisala Digital I/O Unit QMI118 adds 8 digital outputs and 8 digital inputs for sensors, power optimizing, and unmanned control functions based on userdefined requirements.

Innovative in installation

MAWS110 can be equipped with innovative installation aids that significantly lower installation and maintenance costs. A single maintenance person can easily and safely tilt the Vaisala Tiltable Masts.
