Product description: SenseCAP S700-C 7in1 - sensor for building a weather station - Seeedstudio 101991141
The SenseCAP S700-C from Seeedstudio is an integrated weather sensor designed for monitoring local weather conditions in agriculture, meteorology, urban infrastructure, and automation systems. The weather station utilizes radar precipitation measurement, ultrasonic wind measurement, and a photoelectric sensor for global solar radiation and sunshine duration . The wind measurement system's no-moving-parts design reduces mechanical wear, and radiation shields help mitigate environmental influences. Its IP66 rating, wide operating temperature range, and thermostatically controlled heating system allow for use in demanding field conditions.
SenseCAP S700-C 7in1 - sensor for building a weather station - Seeedstudio 101991141.
SenseCAP S700-C is a compact weather station designed for precise monitoring of key atmospheric parameters and solar radiation.
Main features of the SenseCAP meteorological sensor
- Integrated measurement system: records temperature, humidity, atmospheric pressure, wind parameters, precipitation and solar radiation parameters
- Radar rainfall measurement: measures rain intensity without a classic mechanical rain gauge in the range from 0 mm/h to 300 mm/h
- Ultrasonic wind measurement: no moving parts reduce mechanical wear and tear and service requirements
- Solar energy measurement: integrated photoelectric sensor measures global solar radiation in the range of 0 W/m² to 2000 W/m²
- Sunshine duration measurement: enables long-term analysis of access to direct solar radiation
- Weatherproof: IP66 housing allows for outdoor use
- Wide operating temperature range: the device can operate at temperatures from -40°C to 85°C
- Heating system: Thermostatically controlled heating helps keep sensors working properly at low temperatures
- Industrial communication interfaces: RS485 support with Modbus-RTU, SDI-12 and ASCII for easy integration with data loggers, PLCs and computers
- M12 connector: durable, 8-pin connection allows for simultaneous power and data transmission
- 3 m cable: facilitates installation of the station on a mast and connection to recording devices
What does the SenseCAP S700-C weather station measure?
The SenseCAP S700-C provides a comprehensive data set for analyzing local microclimate conditions. It records air temperature from -40°C to 85°C, relative humidity from 0% RH to 100% RH, and atmospheric pressure. from 300 hPa to 1250 hPa. Wind parameters are measured using the ultrasonic method – the station determines wind speed and direction without the use of mechanical vanes or anemometer cups. A radar sensor with an intensity range of 0 mm/h to 300 mm/h and a resolution of 0.01 mm/h is used for precipitation analysis. The S700-C is also equipped with a photoelectric system that measures global solar radiation in the range of 0 W/m² to 2000 W/m² and sunshine duration up to 6553.5 hours. This dataset is particularly useful for analyzing crop conditions, irrigation, solar energy production, the microclimate of urban areas, and local meteorological phenomena.
The S700-C combines the measurement of temperature, humidity, pressure, wind speed and direction, rainfall intensity, global solar radiation and sunshine duration.
Its durable IP66 housing and industrial communication interfaces make it suitable for agriculture, meteorology, automation and Smart City systems.
RS485 and SDI-12 - weather station communication and integration
The SenseCAP S700-C utilizes RS485 and SDI-12 interfaces, popular in measurement systems and industrial automation. RS485 communication supports the Modbus-RTU protocol, allowing the station to interface with PLCs, data loggers, and industrial computers, among others. The manufacturer also supports ASCII communication, which increases the possibility of integrating the device with its own data acquisition system. Connection is achieved via an 8-pin M12 connector and a 3-meter cable that transmits data and supplies power. The station itself does not require wireless transmission, but can be connected to an external SenseCAP LoRaWAN or 4G logger, which is responsible for further measurement transmission. This solution enables the S700-C to be used in both local automation installations and distributed IoT systems for remote environmental monitoring.
