QJ413 All-in-One Weather Sensor

Overview

The Micro Weather Station, also known as an Intelligent All-in-One Weather Sensor, is a compact, high-precision, highly reliable, and maintenance-free multi-parameter integrated sensor. The QJ13 Series adopts an IP66-rated anodized aluminum alloy housing, operates on a 9–30 V DC power supply, and is equipped with military-grade aluminum alloy highly corrosion-resistant connectors for quick and convenient installation. It is capable of measuring ambient temperature and relative humidity, wind speed, wind direction, atmospheric pressure, rainfall, solar radiation, and surface temperature.

Key Features

1.Professional intelligent meteorological sensor with digital RS485 interface.

2.Advanced ultrasonic wind speed and wind direction algorithms ensure full-range measurement coverage and high-accuracy performance across the entire measurement span.

3.The ultrasonic wind sensor offers strong environmental adaptability, ensuring accurate data even under wet, rainy, or water-accumulated conditions.

4.Highly integrated, high-precision, and highly reliable, compliant with CE certification and EMC electromagnetic compatibility testing standards.

5.Equipped with operational status and fault monitoring functions, featuring self-diagnosis and self-recovery capabilities.

Applications

Widely used in new energy power generation, hydrometeorology, and emergency disaster prevention applications
