Michael's Home Instrumentation
- New porch doors have required me to rethink my doorbell!
- We can't hear people knocking on the door
- The people at the door don't know if the old doorbell actually rang
- The old wireless doorbell often didn't ring because the batteries were flat!
- The wireless doorbell didn't require drilling holes in the doorframe - this is a plus
- the 12V battery in the wireless doorbell pushbutton was expensive!
I want to do something simple with the old wireless doorbell and start to develop an extensible home automation/instrumentation project. I have a Nanode and a number of Xinos which I intend to connect on a 4-wire bus around the house.
The old doorbell
Push-button:
- PCB labelled "RL-09 04.04.23"
- Battery 12V A23S "Replaces: 23A, MS21/MN21" A23 on WP cheap 10x pack
- IC1: LP801/V8
Chime unit:
- PCB labelled "RL-09B 04.02.27"
- Batteries 4.5V, 3xAA
- IC2: LP816A
