Abstract: We describe a cloud-based system for monitoring food storage/processing. The system comprises: at least one fixed sensor for installation in an environment to be monitored, configured to collect fixed location environment data relating to the monitored environment; at least one handheld sensor for a user to collect mobile location environment data relating to the monitored environment; and a remote monitoring and reporting system located remote to the monitored environment, to collect the fixed location environment data and the mobile location environment data from the fixed sensor and handheld sensor respectively, and to audit the collected data as coming from the fixed sensor and the handheld sensor.
