This is my new Window/Door Sensor. It is a remake of my other one.

Replaced the CR2032 with two AAA Batteries. In my oppinion the capacity of the CR2032 isnt good ennoth.

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

General

• Powered by 2 AAA Batteries
• Size 23 x 92 (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 Version (10.07.2017):

• adjust dimentions
• Final Test: OK

First Board (internal Test) (30.06.2017):

• Shematic and pcb design ready
• Gerber Files Uploaded
