Seeed Studio SenseCAP S700-C | 7-in-1 Compact Weather Station | Solar Radiation, Radar Rain, Ultrasonic Wind, RS485 & SDI-12, IP66

The Seeed Studio SenseCAP S700-C is a professional-grade 7-in-1 compact weather station measuring air temperature, relative humidity, barometric pressure, global solar radiation (with sunshine duration), rain intensity, wind speed, and wind direction — a complete micro-climate picture from one rugged unit. It pairs a pyranometer, a radar rain gauge, and an ultrasonic wind sensor (no moving parts) with a built-in heater and an IP66 enclosure rated −40 °C to +85 °C — purpose-built for harsh outdoor, agriculture, and smart-city deployments. Data is delivered over RS485 (Modbus-RTU), SDI-12, and ASCII. Core Capabilities 7-in-1 High-Accuracy Sensing Air temperature (±0.1°C), humidity (±1.5% RH), barometric pressure (±50 Pa), global solar radiation (0–2000 W/m², ±3%), radar rain (0–300 mm/h, ±10%), wind speed (0–60 m/s, ±0.3 m/s), and wind direction (0–360°, ±3°). No Moving Parts — Maintenance-Free Ultrasonic wind sensing (0–60 m/s standard, up to 80 m/s withstand) and a radar rain gauge replace spinning cups, vanes, and tipping buckets — eliminating mechanical wear, clogging, and recalibration. Pyranometer Solar Radiation Measures global solar radiation (0–2000 W/m², 300–1100 nm, <1 s response, ±3%) and sunshine duration — valuable for agriculture and evapotranspiration models, solar/PV yield, and climate research. Built for Harsh Climates & Easy Integration IP66 enclosure rated −40 °C to +85 °C with a built-in heater for snow and frost. Outputs RS485 (Modbus-RTU), SDI-12, and ASCII via an M12 connector, powered by 12–24 V at just 0.6 W (21 W when heating). Typical Applications • Smart Agriculture & Agritech: Track micro-climate, solar radiation, and rainfall to guide irrigation, frost protection, spraying windows, and crop-model decisions across fields and greenhouses. • Smart City & Environmental Monitoring: Deploy on poles and rooftops for urban weather, microclimate, and flood-risk monitoring with maintenance-free, heated, all-weather sensing. • Solar & Renewable Energy: Use pyranometer solar-radiation and sunshine-duration data for PV-site assessment, performance benchmarking, and yield forecasting. • Research, Meteorology & Cold Climates: A compact, heated, low-maintenance station for distributed weather networks, hydrology, and sites that see snow and sub-zero temperatures. Technical Integration Key points for wiring the S700-C into your system: • Output & protocols: RS485 (Modbus-RTU), SDI-12, and ASCII via an M12 connector on a 3 m cable; directly compatible with industrial data loggers, controllers, and PLCs. • Cloud backhaul: Pair with a SenseCAP S2100 LoRaWAN data logger or a SenseCAP 4G data logger (sold separately) to send data over LoRaWAN or cellular. • Power: 12–24 V DC (24 V for the heater), at a typical 0.6 W (21 W when heating). • Mounting & environment: IP66 unit (140 × 140 × 350 mm, 1607 g) for pole or cross-arm mounting; operates −40 °C to +85 °C. • Setup help: For sensor selection, data-logger pairing, or integration support, contact the shopioT technical team.

Frequently Asked Questions What does the S700-C measure? Air temperature (±0.1 °C), humidity (±1.5% RH), barometric pressure (±50 Pa), global solar radiation (0–2000 W/m²) and sunshine duration, radar rain intensity (0–300 mm/h), and ultrasonic wind speed (0–60 m/s) and direction (±3°). Can it operate in snow and freezing conditions? Yes. It's rated −40 °C to +85 °C and has a built-in heater (24 V, 21 W when heating) to keep the sensors clear of snow and ice in cold climates. Does it have moving parts? No. Wind is measured ultrasonically and rain by radar — no spinning cups, vanes, or tipping buckets — minimising wear and maintenance. How do I get the data to the cloud? It outputs RS485 (Modbus-RTU), SDI-12, and ASCII via an M12 connector. Pair it with a SenseCAP S2100 LoRaWAN data logger or a SenseCAP 4G data logger, or connect to any Modbus/SDI-12 controller or PLC. How is the S700-C different from the other S700 models? The "-C" version combines both the pyranometer (solar radiation) and the radar rain gauge. S700-A adds radar rain, S700-B adds solar radiation, and the base S700 has neither. How is it powered and mounted? Powered by 12–24 V DC over the M12 cable (typically via the data logger), drawing 0.6 W (21 W when heating). It mounts on a pole or cross-arm and is IP66-rated for permanent outdoor use. Certifications CE EU DOC FCC UK DOC Planning a Weather Monitoring Deployment?
