SensoScientific Sub-1GHz series nodes are wireless environmental monitoring sensors that enable you to launch an independent network infrastructure without Wi-Fi dependence. These long-range, low-power data loggers can be placed directly inside your storage unit, warehouse, refrigerator, and desired location while maintaining connectivity to the 900 MHz gateway. Devices store up to 4,000 readings locally and transmit data to the FDA 21 CFR Part 11 (ERES) validated SensoScientific Cloud for full audit traceability. Sub-1 GHz nodes come equipped with a solid thermal buffer. Whether you are seeking to monitor temperature, humidity, differential pressure, or a combination of parameters, this powerful sensor can document environmental conditions for two separate parameters simultaneously. An optional external wireless display satisfies all CDC and VFC data logger requirements, showing current, minimum, and maximum readings, battery, and alarm status.
