Introduction

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.
