2.2 Installation
To ensure correct operation and reliable and consistent measurements, install the MCF-LW12TER sensor
away from direct sunlight and heating sources like radiators, conveyors, TV, lights etc. and far away from
doors and windows.
The device must be placed where the LoRaWAN® signal coverage is good (SF = 7 optimal, SF = 12 weak).
The sensor must be installed vertically on a wall at about 1.5mt height. It must be at least 30cm away from
metal objects, and 1mt away from electronic devices.
