Temperature and humidity data logger as per SFDA specifications and requirements 

This wireless solution uses Bluetooth Low Energy data loggers to provide continuous visibility of temperature and humidity during transportation of perishable produce in refrigerated vans, trucks and containers. It's ideal for delivery routes, intercompany transfers, couriers and home delivery services, and can also be configured for facility monitoring.

Tzone BLE Loggers wirelessly transmit data and alerts to the smart phone located in the driver's cab. Graphs and PDF files are emailed directly from the mobile device. Tzone loggers can transmit data to a mobile device from up to 30 meters away, which means that when a load arrives the temperature information is quickly retrieved without having to open the doors of a delivery vehicle to locate the device. Users can customize settings, such as name, storage interval, high/low alarm limits and so on.
