Met One AIO 2

Multiparameter weather sensor

Part # 51132

sws sonic weather station

The AIO 2 Sonic Weather Sensor is a complete high performance weather sensor using Met One Instruments’ proven 2D sonic technology. This technology provides reference grade accuracy without moving parts and a built-in compass used for automatic alignment of the sensor.

The temperature and humidity elements are integrated into an IP65 sealed module with a quick disconnect for ease of calibration in the field. The pressure element is precisely calibrated and temperature compensated for outstanding performance.

The AIO 2 is designed for surface meteorological applications where accuracy and reliability matter.

What's the Easiest and Quickest Way to Start Collecting Data and Access it Anywhere?

The Answer's in the Cloud.

eTracker is a cellular modem and "virtual" cloud-based data logger in one (meaning you don't need to install a separate data logger). Simply connect your sensor and a power source to eTracker and you're done. Configure (or reconfigure) anytime from any Internet-connected device, and use Stevens-Connect to retrieve your data, or forward it to your favorite software system.
