CIMTechniques has been using both wired and wireless sensors to monitor temperature and humidity (the environment) where critical materials are processed, stored, and transported since 1997. The CIMScan system detects impending problems and automatically alerts the appropriate personnel before the situation becomes serious. The system is completely web-based and can be accessed from anywhere in the world with the proper credentials using a simple web browser. A small system can be hosted on a workstation class computer on-site or space leased on our server. Larger systems could use a server at a corporate datacenter thousands of miles away.
