Compact weather sensor S700

digitalall-in-oneair temperature

Overview
S700-C 7-in-1 Compact Weather Sensor with pyranometer measures air temperature, relative humidity, barometric pressure, global solar radiation, sunshine duration, rain intensity (radar), wind speed, and wind direction. It is ideal for applications in rough outdoor environments like agriculture or smart cities.
The sensor supports MODBUS-RS485 and SDI-12, interoperable with industrial data loggers, controllers, and gateways. It can be easily integrated with SenseCAP data loggers that support LoRaWAN (SenseCAP S2100) and 4G (SenseACP Sensor Hub).

Key Features

• Multi-parameter measurement — single device monitors temperature, humidity, pressure, light, rainfall intensity, wind speed and wind direction.
• Industrial-grade design — operating range -40°C to +85°C, IP66 protection for outdoor deployment.
• Standard interfaces — RS485 (MODBUS-RTU) and SDI-12 for reliable system integration.
• Thermostatically controlled heating — independent heating supply (24V) for operation in extreme cold.
• Durable, low-maintenance sensors — ultrasonic wind sensors with no moving parts; radar rainfall measurement for high-resolution precipitation intensity.
• Complete kit for installation — includes 3 m cable, pole-mount accessories and radiation shields to ensure accurate ambient readings.

Reliability tests

• Wind tunnel calibration for wind accuracy
• High-low temperature tests for extreme environment performance
• Structural consistency tests across production units
• X-Y-Z vibration tests
• Waterproof and air-tightness (IP) tests
• R&D and production testing to ensure factory pass rates
