Since our trucks travel long distances across the country we have decided to purchase numbers of Data Loggers to equip our cold –chain trucks. that will be appreciated if you can offer a kind of Data Logger with high accuracy which can fulfill our needs based on the following features: *Having temperature sensor on the refrigerator of the truck * Having a panel inside the truck cabin (representing temperature and alarming when it is out of the temperature range) * Temperature sensor and the panel are connected together (Wireless) by Bluetooth or other low energy connections *Temperature sensor and the panel both are portable and data can be recorded and viewed online on the web (remote control). * Collects data but also has access to wireless communications for alarming of events, automatic reporting of data and remote control. * Having GPS * Temperature of refrigerator and location of truck can be remotely controlled online. We would be grateful if you could review and announce the result. Sincerely,Mitra seidizad Show More
