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
