The series includes temperature & humidity sensors, gas sensors, PM2.5 sensors, smoke detectors, and air quality monitoring devices, supporting RS485 communication and real-time environmental data integration for centralized monitoring systems.
Supports temperature, humidity, CO₂, TVOC, PM2.5, methane, formaldehyde, and smoke monitoring applications.
Multiple sensor models support RS485 communication with ModBus-RTU protocol integration.
Designed for long-term operation in commercial buildings, industrial environments, and indoor monitoring systems.
Supports real-time monitoring of CO₂, methane, formaldehyde, smoke, and TVOC concentrations.
PM2.5 sensor uses dual laser measurement technology for particulate monitoring applications.
Supports wide-range DC power input for flexible system deployment and integration.
Compact housing structure suitable for indoor environmental monitoring installations.
