This is my new small Window/Door Sensor.

It works with two Reed Sensors. Additional need is a Magnet.

General

  • Powered by CR2032 3V
  • Size 21 x 69 (mm)
  • Almost SMD 0805
  • Atmel328p TQFP32
  • NRF24I01 smd
  • ATSHA204A chip
  • FTDI, ISP
  • REED Sensors

Description The sensor works with 1 or 2 reed sensors. Why two? This answer is simple. . if you have a Window with two wings you can place the sensor in the middel and it will detect the state of booth.

Settings

  • Use Sensebender Micro bootloader
  • Set Fuses before upload bootloader
  • FUSES: L: 0XDE // H: 0XD2 // E: 0X07 (disabled BOD/8Mhz external clock)
  • Set Fuses again, arduino IDE will override it with the default sensebender fuses or modify the board settings in Arduino IDE

Version

Final (08.12.2016):

  • Test PCB works well
  • Add Code
  • Add 3D printable Case

Beta (14.11.2016):

  • Redesigned
  • Remove step-up and Flash (not usable - save battery)
  • Upload new PCB Files
  • Upload new BOM

Alpha-2 (30.10.2016):

  • Update PCB: Missmatch in Lib fixed
  • Prototyp PCB in production

Alpha (27.10.2016):

  • Update PCB: Clearence
  • Update Shematic: Batt Mon./ prepare ARef for internal VRef
  • Test-PCB Final!
  • Update BOM

Pre-Alpha:

  • Shematic and pcb design ready
  • Gerber Files Uploaded
