pipresencemon is a system utility for Rapsberry PIs that will monitor a GPIO sensor, to determine if a human being is likely nearby. If presence is detected, the screen will be switched on. If no presence is detected, the screen will turn off.
This project requires a sensor; it is currently tested for a PIR sensor. PIR isn't ideal, because it relies on movement. If you stay fairly still, the screen will likely shut down.
The sensor should be connected to GPIO26 / pin 37. Today, the GPIO is hardcoded in pipresencemon.c. This utility is not quite ready to be used by normal human beings, yet. Only developers with a lot of resilience to survive my terrible code should look at this project for the time being.
- To get a build env ready, you can run
make system-deps(the project assumes you already have a cross compiler or build essentials setup). - To build,
make pipresencemon - To regen Wayland protocols,
rm wl_protosand thenmake clean pipresencemon. It will flawlessly, at least 50% of the time.
- Figure out why managing a single display in a multiple display setup breaks
- Capture user interaction for interactive mode
- Hook to dbus to capture wakelock and bcast ambient mode
