Product Description

Wireless thermometer and hygrometer of the WACO system. It is used to measure temperature and humidity in the outdoor environment and to transmit data on temperature and humidity via the WACO radio network. The modules are most often used in the field of measurement and regulation, or in the field of remote reading of consumption meters. The modules are equipped with an external temperature and humidity sensor. The module transmits the current temperature and humidity data via radio messages, either on request (via the “Wake-On Radio” system) or automatically at a set time interval. The report with the value of the instantaneous temperature and humidity read by the thermometer and hygrometer sensor also contains the system time of the module, the battery voltage and the processor temperature.

The transmitted messages are further transmitted via the WACO network to communication gateways of the type WM868-RFU (WACO USB Gateway), WM868-RFE (WACO Ethernet Gateway), or WM868-RFG (WACO GSM Gateway), where they are converted from radio format to communication format via serial line (WM868-RFU), suitable for processing by a local computer, or for communication format over a computer network (WM868-RFE / RFG), suitable for processing by a remote computer.

Alternatively, messages with consumption data can be transmitted to the so-called “collection unit” of the WACO system, which collects data from the WM868-SI / SA / SISA and WM868-TI / TE modules in the WACO radio network, converting the collected data into standard M bus protocol messages -BUS and their further transmission in M-BUS format via the physical bus or in the virtual WACO bus.

The module with a transmitting power of 25 mW is powered by an internal battery with a capacity of 7 Ah.

The modules are equipped with a “Wake-On-Radio” system, which allows communication to be initiated on demand (outside the set interval). With a special radio message (“WOR-packet”), the modules can be immediately switched to the active state and current temperature information can be requested. This mode can be used to obtain instantaneous temperature and / or humidity information using a walk-through reading method (WALK-BY system), or to perform remote diagnostics and configuration of modules via a radio network.
