{"title":"DFRobot Ultrasonic 7-in-1 RS485 Weather Sensor","handle":"ultrasonic-7-in-1-rs485-weather-sensor-wind-rain-temp-light","url":"/products/ultrasonic-7-in-1-rs485-weather-sensor-wind-rain-temp-light","description":"This all-in-one weather station sensor brings seven key environmental measurements into a single outdoor unit: wind speed and direction, temperature, humidity, atmospheric pressure, light intensity and rainfall.It uses ultrasonic wind sensing, so there are no moving parts in the wind sensor, and includes an optical tipping bucket rain gauge for rainfall measurement. Data is provided over RS485 using the Modbus-RTU protocol, making it suitable for Arduino projects as well as PLC, LoRaWAN and other data acquisition systems.The UV-resistant ABS housing is rated IP54, and the wide DC 10V∼30V input gives you flexibility when installing it in the field. DFRobot provides a product wiki and example tutorial to help verify sensor performance and start reading data quickly.The package includes the RS485 7-in-1 Weather Station Sensor x1 and Adapter Cable x1.Features:Professional-grade meteorological sensor: Designed for comprehensive weather monitoring.Replaces 7 separate sensors: Measures wind speed, wind direction, temperature, humidity, atmospheric pressure, light intensity and rainfall.Single cable installation: Uses RS485 for simplified wiring.Arduino/PLC/LoRaWAN compatible: Integrates with Arduino systems, industrial control systems, LoRaWAN setups and data acquisition platforms.Ultrasonic wind sensing: No moving parts for superior accuracy, longevity and minimal maintenance.Optical tipping bucket rain gauge: Highly sensitive rainfall measurement with 0.1mm resolution.Outdoor housing: UV-resistant, IP54 waterproof ABS housing.Example tutorial: Provided for quick sensor performance verification and rapid data access.Specifications:Power Supply Voltage: DC 10V∼30VWorking Current: ＜10mAOutput Interface: RS485Output Protocol: Modbus-RTU protocolMeasured Parameters: Ultrasonic Wind Speed & Direction, Temperature, Humidity, Atmospheric Pressure, Light Intensity, RainfallWind Speed Measurement Range: 0∼40 m/sStartup Wind Speed: 0.5 m/sWind Direction Measurement Range: 0∼359∘Humidity Measurement Range: 0∼99%RHTemperature Measurement Range: −40∘C∼80∘CAtmospheric Pressure Measurement Range: 0∼120 kPaLight Intensity Measurement Range: 0∼200000 LuxRainfall Intensity Measurement Range: ≤4 mm/minWind Speed Measurement Accuracy: ±(0.5+2%FS) (60%RH,25∘C)Wind Direction Measurement Accuracy: ±3∘ (60%RH,25∘C)Humidity Measurement Accuracy: ±3%RH (60%RH,25∘C)Temperature Measurement Accuracy: ±0.5∘C (25∘C)Atmospheric Pressure Measurement Accuracy: ±0.15 kPa (101 kPa,25∘C)Light Intensity Measurement Accuracy: ±7% (25∘C)Rainfall Measurement Accuracy: ±4%Rain Gauge Resolution: 0.1mmWind Speed Response Time: 1sWind Direction Response Time: 1sHumidity Response Time: ≤25sTemperature Response Time: ≤8sAtmospheric Pressure Response Time: ≤2sLight Intensity Response Time: ≤2sHumidity Long-Term Stability: ≤1%/yearTemperature Long-Term Stability: ≤0.1∘C/yearAtmospheric Pressure Long-Term Stability: −0.1 kPa/yearLight Intensity Long-Term Stability: ≤5%/yearProtection Level: IP54Housing Material: ABS Polymer PlasticSensor Cable Length: 14cmAdapter Cable Length: 150cmIdeal for smart agriculture and greenhouse automation, including ventilation control, rainfall-based irrigation, natural light monitoring and frost-risk trend tracking.","vendor":"DFRobot","product_type":"Weather Station Sensor","in_stock":true,"options":[],"variants":[{"id":15959,"title":"Default Title","sku":"DF-SEN0657","mpn":"SEN0657","price":612.2,"on_sale":false,"in_stock":true,"available_quantity":24}]}
