Data logger on raspberry pi with 3G router

We're testing a vending machine and need to monitor the pressure switches (these are just simple switches, 4 of them). These triggers would simply be high/low inputs on the GPIO's.

We'd like to use a raspberry pi to take the triggers (as they occur) and then send the info via SMS with the Pi's MAC ID. This will allow us to see if the machine has overpressured.

We already have the 3G routers so just need the raspberry pi code to monitor the pressure switches and send SMS or email when they're triggered.

If this project goes well, I have at least 3 other projects that will be much more challenging and with bigger budgets.

This is a guaranteed project for the right applicant.


Hi everyone,

Some ore info that may help you in your quotes. We'll be using a proroute 3g router. it connects to the ethernet of the rasp' pi. Here's a link.

The pressure sensors will be IFM pressure switches. Here's the link.

I'm not precious about messaging being via text. We currently use temboo and send emails to gmail. happy to use that format again if it's easier for you guys.

We may want to create log files of the data acquired by the sensors. this can be something we can convert to a graph in an excel spreadsheet.

Hope this helps.
