Bring multiple environmental measurements into one rugged field sensor for Arduino, IoT and monitoring projects. This 9-in-1 unit measures ultrasonic wind speed and direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise, PM2.5 and PM10.
Ultrasonic wind sensing means there are no moving parts to wear out, helping reduce maintenance for outdoor deployments. The sensor is built into a UV-resistant, waterproof ABS polymer plastic housing with an IP54 protection rating, and it accepts a wide DC 10~30V power input for flexible installation.
Data is sent over RS485 using the Modbus-RTU protocol, making it suitable for PLCs, data loggers and IoT platforms such as LoRaWAN gateways. An Arduino example tutorial and product wiki are provided, and the package includes the RS485 9-in-1 Weather Station Sensor and an adapter cable.
Typical applications include meteorological observation, smart agriculture, greenhouse management, industrial automation, maritime monitoring, urban air-quality stations and smart building infrastructure.
Features:
- 9-in-1 sensing: Measures ultrasonic wind speed, wind direction, air temperature, relative humidity, atmospheric pressure, light intensity, noise levels, PM2.5 and PM10.

Jargon buster
Plain-language definitions for the technical terms used above.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- IP54
- An ingress protection rating meaning the enclosure has limited dust protection and is protected against water splashes from any direction. This matters because it gives a practical indication of how well the product may handle dusty or damp installations.
- lux
- Lux is the standard unit for measuring how much light falls on a surface, similar to how a light meter reports brightness. A sensor that outputs lux gives readings that are easier to compare between rooms, outdoor conditions, and different projects.
- Modbus
- Modbus is an industrial communication protocol used by many meters, sensors, PLCs, and automation devices. Modbus support matters because it can make the controller easier to integrate with existing industrial equipment.
- ModBus-RTU
- ModBus-RTU is a common industrial protocol for sending sensor readings and control commands over serial links such as RS485. Knowing the sensor uses ModBus-RTU helps you choose software libraries, data loggers, or controllers that can request and interpret its readings.
- PM10
- PM10 refers to airborne particles with a diameter of about 10 micrometres or smaller. It includes larger dust and pollen-like particles, so it is useful for detecting coarser airborne pollution.
- PM2.5
- PM2.5 refers to airborne particles with a diameter of about 2.5 micrometres or smaller. It is a common air-quality measurement because these fine particles can be breathed deep into the lungs.
- RS485
- RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
