ASR Differential Barometer/Altimeter OEM Module (LoRaWAN 915 MHz)

The DBOxxx series differential barometer/altimeter (patent pending) is a higher accuracy version of the EMOxxx. This OEM module provides atmospheric pressures and derived elevations at a rover using corrections transmitted from a stationary base. In traditional systems elevations are calculated based on pressure readings for a stand-alone unit and are subject to the errors inherent with environmental changes in pressure. Some applications of this versatile engine include indoor elevations, building pressurization monitoring, multi-node telemetry networks and UAV altitude references. A minimum of two units are required for a differential solution, the price listed is for a single unit.
