Methods and apparatus for monitoring remotely located objects with a system comprised of at least one master data collection unit, any number of remote sensor units, and a central data collection server are described. The master unit is configured to monitor any object, mobile or stationary, including monitoring multiple remote sensor units associated with the objects being monitored. The master unit may be in a fixed location, or attached to a mobile object. The master unit is configured for monitoring objects that enter and leave the area where it is located. The master unit may act as a parent controller for one or more child devices, wherein the child devices can be remote sensors or monitors of various measurable conditions including environmental conditions, substance identification, product identification and biometric identification. The master unit is able to discover new remote sensor units as they enter or leave the area where the master unit is located. The master unit can be remotely reprogrammed. The reprogramming can be accomplished with authenticated instructions.
