US Patent 7630864 Temperature and humidity monitoring for pharmacy shipping crate

A monitor device is attached onto or inside a shipping crate for pharmaceutical shipments and monitors the temperature and/or humidity within the crate in transit to identify whether the contents are safe or compromised. A keyboard/display on the device provides an ID code that the recipient enters into a computer web page to communicate this ID code to the shipper or to a third-party agency. If the ID code represents a safe shipment, the shipper or third-party returns an acceptance message. If there has been a compromise, a different ID code is presented, and the web page instead returns a message to return the crate. A return envelope can be included for the recipient to return the monitor device to the shipper.
