A LAN-based data logging system was integrated by OTM for air temperature, relative humidity, barometric pressure, and air speed monitoring. The following instruments were used:
- HD50GH: web data logger supporting 4 analog inputs and ethernet connectivity
- HD2001.1: temperature, humidity and pressure transmitter with 4-20 mA output
- HD403TS2: air speed probe with 4-20 mA output



All data loggers in the network automatically upload the results to a server in the LAN periodically. Shown below is the result viewer in the HDServer1 software. The data logging network can be expanded with more loggers added.





What are the advantages of using a LAN network for environmental data monitoring compared to other methods?
