1. Description
The EGK-LW22CCM is a IP65 battery powered device for temperature and humidity measurements.
This small-sized device is designed for all situations where it is necessary to keep temperature and
humidity under control, from catering to medical and pharmaceutical applications, from museum
environments to vaults and wine cellars. The multifunction button and the colored LEDs, combined
with the Bluetooth connection, guarantee ease of configuration and control. The device can store up
to 3000 sets of historical data records with time stamps, even without connection. Historical data can
be retrieved via Bluetooth by LoraTool App or via LoRaWAN network by uplinks.

2.2 Installation
To ensure correct operation and reliable and consistent measurements, install the EGK-LW22CCM
sensor away from direct sunlight and rain.
The device must be placed where the LoRaWAN® signal coverage is good (SF = 7 optimal, SF = 12
weak). The sensor can be installed on the wall or pole using the included accessories.
Custom brackets available on request.
2.2.1 Wall mount
The fasteners and substrate surfaces should have equilibrated for a minimum of 1 hour at
temperatures of 68°F (20°C) or greater before application. These adhesive backed fasteners should
be applied to surfaces that are smooth, dry and free of oils, mold release agents or other surface

contaminants. The substrate should be cleaned with an appropriate cleaning method for the
customers substrate(s) and surface contaminant(s).
NOTE: Be sure to follow the manufacturer’s precautions and directions for use when using solvents, or
other cleaning method.
Remove the liner and without touching the adhesive, apply the fastener the surfaces using firm roller
pressure to help ensure complete adhesive contact to the substrate. The pressure-sensitive adhesive
bonds on contact and parts can be handled immediately. Adhesive bond strength increases with time,
pressure and temperature. A minimum of twenty four (24) hours dwell is recommended before
applying a load or disengaging. Recommended time to achieve maximum bond strength is 72 hours
(3 days).

2.3 Power ON/OFF
The sensor is shipped completely off to prevent battery consumption during storage. It is therefore
necessary to carry out a first power-on prior to commissioning.
To power on the sensor: lay the magnet at the bottom of the provided tool into the area shown in the
figure:
