Ethernet Temperature and Humidity Data Logger

An industrial-grade data logger that uses existing Ethernet infrastructure to centralise temperature and humidity monitoring across buildings and sites. The RJ45 port supports static or DHCP addressing, cross-gateway communication, DNS resolution and DDNS, so data can reach servers on the local network or across the wide area network. A large LCD shows live readings, user-defined upper and lower limits drive a built-in buzzer or relay alarm, and calibration is password protected. With ±0.5 °C and ±3 %RH accuracy, a 1-second refresh, 65,000 records of internal storage and strong resistance to electromagnetic interference, it suits server rooms, power rooms, hospitals and security systems.
