The device size is 44 mm x 37mm x 20mm.

• On Board the device are:
• AM312 (PIR Sensor)
• BH1750FVI (Ambient Light Sensor)
• Atmega328
• 8MHz crystal oscillator (for DIY)
• three-color led
• nrf24l01
• AT25F512B-SSH-T (flash)
• ATSHA204A_SOT23 (cripto)
• TPS627ХХ family (consumption of 360 nA)
• two 14250 batteries (7.2v 1000mA)
• FTDI (micro)
• ICSP (micro)
• Two side buttons (first button-reset, the second button - interrupt (DIY)
• Power switch

FTDI/ICSP adapter - gift.

Very long life on one set of batteries -> 3 years

What can this motion sensor do:

• Firmware by air.
• Work on all bootloaders.
• Sending the status of the motion sensor to the controller
• Three modes of motion sensor (Night | Day | 24 hours)
• Adjustable delay (without delay | 1minute - 4 hours)
• Sending the remaining battery charge as a percentage
• Sending the illumination level in Luxs

Configuring via the Mayensors module in Majordomo (...and through any other controller):

• The interval for sending the remaining battery charge
• Lighting level sending interval
• Setting the operating mode of the signal led (RGB) - Hidden mode | Red | Green | Blue
• Adjusting the level of the illumination limit at which the motion sensor will work
• Set the time delay for the trigger of the motion sensor in the active state. In the same way, the restart of the specified interval is applied programmatically in case of repeated movement during the already detected motion detection.

On board there is a cryptographic board atsha204a-stucz-t There is also an external SPI Flash AT25F512B-SSH-T A very interesting down-converter 3.3-10v in 3.3 is used in a very low own consumption of 360 nano-amperes | Dual-cell Ultra Low IQ Step Down Converter for Low Power Wireless Applications |

Output as FTDI and ICSP, so that complete freedom in manipulating the device. You can use my software. You can write a cool their software. I'm all for it!!!

If all this is described in a nutshell = the device is working cool :)

As a smart home controller, I now use the Majordomo system, it's a full-fledged home Web server on Apache. Screen of the traffic sensor in the Mayensors module in the Majordomo system
