The POE smart temperature/humidity sensor has an RJ45 network interface and supports power from a POE switch or an external terminal block. An integrated TCP/IP stack provides 10M/100M auto-negotiation and UDP, TCP Server and TCP Client modes, plus a built-in Web server. A browser gives direct access to real-time temperature/humidity data, historical trend plots and CSV history export. Host-computer software allows parameter adjustment and data monitoring. The Web server supports simultaneous access by multiple users for convenient remote monitoring and history export. Flexible use, POE power, high measurement accuracy, a wide measurement range and good data consistency suit many applications. Robust protection includes first-level lightning protection.
