The probe and housing are integrated into a single waterproof unit for straightforward deployment in rivers, lakes, ponds and other monitoring sites.It uses a fibre optic light path design with a filtering algorithm to help resist external light interference. The sensor is factory calibrated before shipping, so it is ready to use without further calibration.Data is output over RS485 using the standard ModBus-RTU protocol. DFRobot provides tutorials for connecting the sensor to Arduino development boards and DFRobot LoRaWAN setups, making it suitable for real-time monitoring and long-term IoT environmental data logging.The package includes the RS485 Water Quality Blue-Green Algae Sensor and a 5m sensor cable.Features:Measurement range: 0~400 μg/LResolution: 0.1 μg/LAccuracy: ±5% FSIntegrated probe housing design: waterproof rating up to IP68Fluorescence principle with filtering algorithm: strong resistance to external light interferenceBuilt-in temperature sensor: automatic temperature compensation to ensure measurement accuracyRS485 communication interface: supports ModBus-RTU protocolSpecifications:Power Supply Voltage: 10~30V DCPower Consumption: 0.4WCommunication Interface: RS485 (Standard ModBus-RTU protocol)Measurement Range - Cyanobacteria: 0~300,000 cells/mlMeasurement Range - Temperature: 0°C~+60°CMeasurement Accuracy - Cyanobacteria: ±5%FS (25℃)Measurement Accuracy - Temperature: ±0.5°CResolution - Cyanobacteria: 1 cell/mlResolution - Temperature: 0.1°CLinearity: R²>0.999Temperature Compensation Range: 0°C~+60°CResponse Time: ≤30SOperating Temperature: 0°C~+40°CMeasurement Principle: Fluorescence methodWaterproof Rating: IP68Pressure Resistance: 0.6MPaCable Length: 5mHousing Material: Corrosion-resistant plasticUseful for harmful algal bloom early warning, aquaculture water monitoring and remote ecological research with LoRaWAN nodes.","vendor":"DFRobot","product_type":"Water Quality Sensor","in_stock":true,"options":[],"variants":[{"id":15906,"title":"Default Title","sku":"DF-SEN0714","mpn":"SEN0714","price":1352.25,"on_sale":false,"in_stock":true,"available_quantity":7}]}
