LORAWAN COMPATIBLE

Monitor conditions in harsh environments

Monitor temperature and relative humidity outdoors, in rain, and in freezers down to −40°C. The LR690 is built for demanding locations such as remote technical sites, equipment enclosures, storage areas, and utility facilities. With a compatible gateway, readings reach your monitoring system for review and action.

No external cables. Place it and it's ready.

Both sensing elements are inside the LR690 — there are no external probes, leads or cabling to run, route or protect. Fix the unit in place, power it on, add it to your gateway, and it starts reporting.

Fewer parts mean faster installation, nothing exposed to damage outdoors, and a cleaner, more reliable deployment.
