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.
