Product description: SenseCAP S800 V2 8in1 - sensor for building a weather station - Seeedstudio 101991023

SenseCAP S800 V2 is an advanced weather sensor designed to provide precise and comprehensive monitoring of environmental conditions. It measures eight key parameters: air temperature, relative humidity, atmospheric pressure, wind speed and direction (using ultrasonic technology), PM2.5 and PM10 concentrations and noise level . It is designed to work in extreme conditions, its operating temperature range is from -40°C to 85°C, and its tightness class is IP66 . The sensor uses RS485 (MODBUS-RTU) and SDI-12 interfaces , which facilitates its integration with various data recording systems. The set also includes a 3 m cable , a USB Type-C cable , mounting screws and a flat washer to open the communication port.

The manufacturer has prepared a user's guide that makes it easier to start working with the sensor.

The sensor is used to monitor up to 8 environmental parameters.

Main features of the sensor

  • Enables measurement of eight environmental parameters: air temperature, relative humidity, atmospheric pressure, wind speed and direction, PM2.5, PM10 concentration and noise level
  • It provides high resistance to difficult weather conditions thanks to the IP66 tightness class
  • Offers support for RS485 (MODBUS-RTU) / SDI-12 interfaces
  • It is equipped with a thermostatically controlled heating system, enabling operation in extremely cold conditions
  • It uses ultrasonic sensors to measure wind speed and direction, which reduces the number of moving parts used in the structure
  • It is designed to operate in a wide temperature range from -40°C to 85°C

Applications of the SenseCAP S800 V2 sensor

The SenseCAP S800 V2 sensor is used in many areas, such as agriculture, where it helps optimize conditions for crops . In the context of smart cities, this device facilitates the management of air quality and noise levels , which translates into improved living comfort of residents. Moreover, it is an invaluable tool in the energy and transport sectors, as well as in meteorological monitoring, where its ability to precisely forecast weather significantly supports decision-making.

SenseCAP ONE sensors

The SenseCAP ONE series of weather sensors are compact devices that users call "all-in-one". They include a wide range of sensors that enable monitoring as many as 10 key weather parameters - air temperature, air humidity, atmospheric pressure, light intensity, wind speed and direction, precipitation, PM 2.5 and PM 10 concentration and CO2 level . This comprehensive solution allows for highly precise tracking of atmospheric conditions in one compact device (the ability to measure individual values depends on the selected sensor model).

Reliability tests performed before the product is released to the market.

High reliability of SenseCAP sensors

Seeedstudio products are characterized by high quality and reliability , which is confirmed by numerous tests carried out at the production stage. Before the modules are finally released from the factory, the manufacturer conducts a series of tests to ensure that the modules will function perfectly in extreme conditions throughout their entire life cycle. The SenseCAP ONE series has passed 6 reliability tests , which include:

  • Wind tunnel - measurement of wind direction and speed in an artificially changing environment,
  • High and low temperature test - determines operation in extremely unfavorable temperature conditions,
  • Structural test - determines whether the collected values from multiple devices are consistent and highly precise,
  • Three-axis vibration test (xyz) - assesses the impact of vibration on sensor measurements,
  • Waterproofness and tightness test - checking whether the module meets the requirements for operation in a difficult environment,
  • R&D and production test - to check the performance of multiple devices in factory conditions.

Modbus RTU RS485 and SDI-12 communication protocols

RS485 is a data transmission standard enabling serial communication over long distances and in difficult environmental conditions . It is often used in industrial systems due to its ability to maintain reliable communication even in the presence of electromagnetic interference.

SDI-12 is an interface standard for connecting microprocessors with environmental sensors, where the number "12" means 1200 baud, i.e. the data transmission speed. It is particularly popular in environmental monitoring applications because it allows multiple sensors to be connected to a single data recording device simply and efficiently .
