CMG-D22-LoRaWAN Displacement sensor
Measures displacement, stores results, and transmits them over LoRaWAN on schedule. Battery operation supports autonomous monitoring points.

Application and connection
CMG sensors monitor crack and expansion-joint opening and relative vertical or horizontal movement between structural elements.
The CMG-D22 uses LoRaWAN and has non-volatile memory for autonomous logging. Data is recorded in a file accessible from a PC over USB. Without a base-station connection it operates as a standalone logger; the manufacturer specifies memory sufficient for several years of recordings.
