Abstract: Aspects of the present disclosure describe apparatus, methods and systems for monitoring the operational status of fire extinguishers through the utilization of optically sensed, color profile determinations of a pressure gauge positioned on the fire extinguisher as well as the utilization of vibrational, and location sensing devices. Advantageously, monitoring apparatus according to the present disclosure are networkable, and a number of their operational characteristics may be configured via the network and associated servers. Furthermore, monitoring apparatus according to the present disclosure may employ vibrational, acceleration, GPS, RFID, and ultrasonic sensors to detect movement, location, and obstructions. In sharp contrast to the prior art, apparatus, methods and systems according to the present disclosure operate with existing fire extinguishers and provide a convenient, cost effective, and highly functional upgrade path for deployed fire extinguishers.
