To get a grab hold of the data and notify us in certain conditions, we planned to interface the raspberry pi3 to the NODE-RED online platform.
By doing so we can program it to send the obtained data directly to our e-mail on pre determined conditions.

For example if the temperature of the refrigerated meat is over a certain threshold, An alert can be triggered to notify the relevant personnel.
Here is a actual view of the online NODE - RED platform to connect the datas from raspberry pi3 to our e-mail.

We had to do some programming to keep our device running perfectly ,so that the email service is being triggered on apt conditions

Below here is the actual snippet of the coding to set up a threshold value as a trigger point.

On deploying the code we were finally able to finish the loop of getting data ,using raspberry pi3 as gateway device by communicating with the cloud to get data logs on client's devices.

Here is our final hardware for this setup
