The Wireless Doorbell is based on this boards:
X-NUCLEO-IDS01A4 (868 MHz)
of course are necessary two kits.

How to use this doorbell

  • First, compile and download on TX the relative TX SW and on RX the relative RX SW.
  • Second, on the RX kit, connect a Alarm Buzzer to:
    GND and
    Pin n.6 on connector CN9 present on the X-NUCLEO-IDS01A4
    See the image below.

    In practice the buzzer is connected to the PB_4 that is the same output that drive the Red Led present on the X-NUCLEO-IDS01A4 evaboard.
  • Third, on the TX kit, connect a push button at the pins listed below:
    GND and
    PC13 (connector CN7 on the NUCLEO board)
    See the image below.

    In practice we use the same pin (PC_13) where is connected the Blue Button present on the NUCLEO-L053R8.

For this project we have used the X-NUCLEO-IDS01A4 that cover some tens of meters (it use a small integrated antenna).
If you need cover 50…100 meters, we suggest to use the SPSGRFC – available at 433, 868 or 915 MHz MHz – (UFL connector for external antenna + SPIRIT1).
The SW don’t change, change the distance that you cover that increase a lot.

Some HW modification

If you have already a DoorBell installed in your home and you need install a new internal ringer you must use this project.
It is necessary only substitute the Push Button, with a relay connected in parallel to your current internal ringtone.
Of course choose a relay with appropriate work voltage compatible to your internal ringtone.
See the schematics below.
