# 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
