STM Smart Temperature Monitoring Device

Intelligent Temperature Surveillance with IP68 Protection for Indoor, Outdoor & Subterranean Deployment

STM is an intelligent temperature data acquisition device featuring IP68 certification for deployment across indoor, outdoor, and underground locations. Equipped with specialized temperature sensors providing continuous monitoring and configurable transmission intervals (5 minutes to 1 hour), STM communicates via LoRaWAN or NB-IoT networks with integrated antenna. Internal data logging and adjustable preset value messaging make STM ideal for cold storage facilities, multi-zone infrastructure, and commercial temperature-critical operations.
