Product information "CL-211-E PM2.5/CO/Temperature/Humidity Data Logger, RS-485 & Ethernet PoE"
The CL-211-E CR is a data logger module that records PM2.5, CO, temperature, humidity and dew point readings, each stamped with date and time. It stores up to 450,000 downloadable records, giving engineers an auditable history of indoor air or storage conditions.
Connectivity is provided by an RS-485 port and an Ethernet port with PoE, supporting DCON, Modbus RTU, Modbus TCP and MQTT. Live data can be viewed across the same local network using the free Windows software or the iOS and Android apps, and the module can be integrated into existing HMI or SCADA systems. An onboard relay output (1 x Form A, SPST) can drive an alarm or an indoor air quality control device.
Typical deployments include food and pharmaceutical transport, HACCP-controlled food and beverage sites, building and energy management, warehouses, museums and archives, and monitoring of indoor or underground car parks. The module is rated IP20 for ceiling or wall mounting, with an operating temperature of 0 ~ 50°C.
Applications
- Transportation of food or pharmaceuticals
- Food and beverage industry (HACCP)
- Blood stations and pharmacies
- Building and energy management
- Warehouse management
- Museums, archives and galleries
- Indoor or underground parking lot air quality monitoring
