SLMS Train Sensor

A software toolkit for the Raspberry Pi Sense Hat to enable us to detect when a train is passing overhead.

Currently doesn't do that and simply displays the accelerometer data on the RGB matrix display.

Clone the repo then simply run

$ python sensetrain.py high

To enable high sensitivity readings to be displayed.

From picking it up and shaking it around:

Bill of materials (BOM)

• [Raspberry Pi] (http://bit.ly/2nyBJ3V)

• [Raspberry Pi Sense Hat] (http://bit.ly/2nE67L2)

Alternative BOM

A solution based on the ubiquitous NodeMCU (ESP8266 arduino compatible wifi enabled board) with ADXL335 accelerometer module should come in ten times cheaper.

Untested code in the arduino folder.
