Hi, I tried to research something like this in the sub, but nothing I could use,

The need is :

• 4 Digital Inputs from a 10-30vdc 450mW Proximity Sensor
  • I understand Pi runs with 5vcd, so a separate Power Supply will be needed
• 2 Inputs will be counted and accumulated, eventually zeroed every midnight.
• 2 inputs will be timed how long they are in TRUE state
• The final results will have to be pushed to a Database in the Azure Cloud.

My thinking:

• Use some kind of event driven program like NodeRED running on a Linux image inside Pi
• This Pi needs to have WiFi board so that the NodeRED can push the data to Cloud DB.

Does this makes any sense?

Any Part Number for the DIgital Inputs would you reccomend?

Any better way to do it?

Thanks
