Homie-RCWL

RCWL-0516 radar occupancy sensor with esp-01s. Using MQTT with homie convention to transmit data.

Notes

Use RX pin on ESP-01 for input because GPIO0 and GPIO2 seem to cause boot issues because of internal pull up resistors.
The 3v3 output pin on the RCWL does not supply sufficient current to power ESP-01
RCWL is 5v powered
