RepeaterPi

• Project to monitor sensors inside of a repeater cabinet and alert trustees when a argument is tripped

• Link to source code

Software Arguments

• The following arguments may be added to modify the software's behavior.

  • --copyright will print out the legal notice for using this software.
  • --test will run the software in a 'dry run' mode for the purpose of continuous integration.

The sensor board

• The sensor board is a small Arduino based device that has two voltage probes and a TMP36 analog temperature sensor. The diagram can be found here
• All three of the sensors are analog therefor requiring that they be connected to the Arduino via it's analog pins.
  • It's up to the user to deicide how they want their sensor board to be hooked up.
  • The only requirement is that the TMP36 be connected to A1, the main voltage probe be connected to A6, and the amplifier probe to A7.
  • However it is easy to change this to your discretion. Just edit the first three lines in the Arduino sketch, named RepeaterPi.ino

Calculating Sensor Readout

• Because these are not digital readouts, conversion from voltage is required.
  • The formula for the voltage probe:
    • (V * (61/11))
  • The formula for the TMP36 temperature probe:
    • ((mV- 500) / 10)
