Senlab O is a smart wireless module, featuring the LoRaWAN connecvtivity protocol.
4 functionalities "All in One" transmission:
This device is designed to log temperature, relative humidity of the air, luminosity and presence.
Designed for indoor use,
this Senlab offers a small form factor and discreet aesthetics
that make it ideal for the home or office.
'This Senlab offers the best in class features as:
• Battery Life time
• Rich data content thanks to datalogging (12 data/radio transmission)
• Radio performances
• Advanced set of functionalities
• "over the air" activitation and reconfiguration

Uses Cases
Smart Building
office comfort monitoring
space optimization (presence monitoring)
Ocuppancy rate
Energy efficiency
