Mini Weather Station
The SEVEN Mini Weather Station is designed specifically for monitoring PV facilities, providing an easy-to-install and durable solution suitable for field conditions. It can read the following data:
1- Horizontal Wind Speed
2- Horizontal Wind Direction
3- Ambient Temperature
4- Relative Humidity
The aluminum parts of the sensor are coated with anodized protection, and the plastic parts are made from ABS for enhanced durability. SEVEN Mini Weather Station is available in three models to meet varying customer needs:
3S-WS&D: Measures Wind Speed and Direction
3S-AT-WS&D: Measures Wind Speed, Direction, and Ambient Temperature
3S-RH&AT-WS&D: Measures Wind Speed, Direction, Ambient Temperature, and Relative Humidity
Category: Compact Weather Station
