Description Overview Compact Weather Sensor integrates temperature, humidity, noise, PM2.5/PM10, and illuminance measurement.Equipped with RS485/Modbus RTU and optional SDI-12 for flexible data output. IP65-rated protection ensures reliability in harsh outdoor conditions.Ideal for environmental monitoring, smart agriculture, and IoT applications. Features Multi-parameter monitoring – Measures temperature (-40°C to 85°C / -40°F to 185°F), humidity (0–100%RH), noise (30–130 dB), PM2.5/PM10 (0–500 µg/m³, extensible to 1000 µg/m³), and illuminance (0–100K Lux). High accuracy – Temperature ±0.3°C (±0.54°F), Humidity ±3%RH, Noise ±1.5 dB, Illuminance ±3% or 1% F.S, PM2.5/PM10 ±(10 10%) µg/m³. Fast sampling frequency – 1 Hz real-time updates for all parameters. Robust design – IP65 protection with radiation shield (PC fiber with thermal insulation) to minimize solar interference. Advanced noise sensing – Uses high-precision electric pickup with A-weighting method. Laser scattering technology – Ensures reliable detection of fine particulate matter (PM2.5/PM10). Illuminance detection – Equipped with optical elements covering 400–1100 nm wavelength range with filtering. Flexible data output – Standard RS485 Modbus RTU, optional SDI-12 for custom setups. Power-efficient operation – Works on DC 9–24V with low consumption. Mounting options – Sleeve fixed, optional 1.5 m / 1.8 m trestle brackets (extra cost). Cable flexibility – Comes with 3 m standard cable, optional 10 m extension available. Durable build – Compact design, built for outdoor environments with -40°C to 80°C (-40°F to 176°F) operating range. Long service life – Backed by a 3-year warranty from XinFeng.
