Product Description

The Dragino WSS-03 is a comprehensive RS485 air quality sensor designed for accurate environmental monitoring. It is part of the Dragino Weather Station solution and is capable of simultaneously monitoring carbon dioxide (CO2), particulate matter (PM2.5), and particulate matter (PM10) levels. The sensor is equipped with a weatherproof shield, ensuring protection against UV light and radiation, making it ideal for outdoor use in various weather conditions. The WSS-03 is designed to be integrated into the Dragino Weather station ecosystem, where it connects via an RS485 interface to the WSC1-L main processor. This integration allows for the transmission of environmental data to an IoT Server through wireless LoRaWAN protocol.

Product Features

  • RS485 Interface: Ensures reliable data transmission within the weather station system.
  • Multi-Parameter Monitoring: Capable of measuring CO2, PM2.5, and PM10 simultaneously.
  • Weatherproof Design: Equipped with a shield for protection against environmental elements like UV light and radiation.
  • Integration with Dragino Weather Station: Designed to be part of a comprehensive weather monitoring system.
  • Wireless Data Transmission: Utilizes LoRaWAN protocol for sending data to an IoT Server.
  • Wide Measurement Range: Can measure CO2 levels from 0 to 5000 ppm and PM2.5/PM10 levels from 0 to 1000 μg/m3.
  • High Accuracy: Offers an accuracy of ±3%F•S (25℃) for both CO2 and particulate matter measurements.
  • Dual Temperature Range Operation: Operates in a temperature range of 0℃ to 50℃ for CO2 and -30℃ to 50℃ for PM measurements.
  • Low Power Consumption: Requires only 50mA@ 12v, making it energy efficient.
  • Compact Dimensions: Measures 178 mm × 140 mm × 140 mm, facilitating easy installation in various locations.

The Dragino WSS-03 is a versatile and reliable choice for environmental monitoring, particularly in applications related to weather stations and air quality assessment​.
