Ultrasonic 9-in-1 RS485 Weather Sensor for Arduino (Wind, Temp, Light, Noise)

The Ultrasonic 9-in-1 RS485 Weather Sensor provides comprehensive meteorological monitoring across nine environmental parameters within a single, integrated unit. Designed for Arduino enthusiasts, agricultural engineers, and smart city projects, it delivers accurate real-time data without the complexity of wiring multiple standalone modules.

Solid-state ultrasonic multi-parameter sensing

This sensor simultaneously records wind speed, wind direction, temperature, relative humidity, atmospheric pressure, light intensity, ambient noise, PM2.5, and PM10 particulate levels. Ultrasonic wind sensing uses no moving mechanical parts, preventing physical wear and eliminating the need for routine on-site calibration.

Weatherproof IP54 outdoor housing

Constructed from UV-resistant and waterproof ABS polymer plastic, the enclosure protects internal electronics in challenging outdoor environments. A wide input voltage range of DC 10V to 30V allows versatile installation across agricultural, commercial, and industrial sites.

RS485 Modbus-RTU data transmission

Data output relies on standard RS485 with Modbus-RTU protocol for stable, long-distance communication with microcontrollers, PLCs, and LoRaWAN gateways. Arduino example code and documentation are provided to streamline software development and rapid bench testing.

Diverse deployment applications

The sensor is well suited for greenhouse automation, municipal air quality tracking, weather research, and maritime installations. Its multi-variable payload provides a complete operational picture for remote environmental monitoring systems.

Included cabling and hardware

The package includes one RS485 9-in-1 weather station sensor with a 14 cm integrated lead and a 150 cm adapter cable for wiring into your control hardware.
