Air temperature and humidity sensor –
THS SENSOR 40 12DC LAN

Description

The THS SENSOR 40 12DC LAN is an air temperature and humidity sensor with Ethernet LAN interface for transmitting the measured values to a master device. It can be used in computer controlled measurement systems or as a peripheral device to a large-size LED display, which displays the measured values.
