Product Introduction
The MINI Ultrasonic Environmental Monitoring Instrument is a highly cost-effective miniature meteorological and environmental monitoring device developed by our company. It features low-power chips and circuit design, with a power consumption of only 0.2W for conventional 5 elements and 0.45W for 6 elements (including rainfall). This makes it particularly suitable for environments powered by solar energy or batteries, where power consumption requirements are strict. With its newly designed structure, the device is more compact, with a diameter of approximately 8 cm and a height of about 10 cm (for the conventional 5 elements).
The MINI Ultrasonic Environmental Monitoring Instrument innovatively integrates six environmental monitoring elements—wind speed, wind direction, temperature, humidity, air pressure, and rainfall/light intensity/solar radiation (one of the three selectable)—into a compact structure. It outputs all six parameters to users at once through the 485 digital communication interface, enabling continuous 24-hour online monitoring in outdoor environments.
This device is suitable for various fields, including agricultural meteorology, smart streetlights, scenic area environmental monitoring, and highway meteorological monitoring.

Notes：
The north arrow indicates magnetic north, which is not completely aligned with geographic north. Therefore, when calibrating the sensor, the deviation (error) at the specific location must be taken into account.
Deviation depends on location, with a maximum error potentially exceeding 15° (e.g., in northeastern regions). In regions such as eastern China, the deviation can be considered negligible (<3°). For more detailed information on this topic, you can refer to resources available online.
The ultrasonic wind sensor is a precision instrument. Handle with care and avoid impacts or collisions.
