I present my new device-motion sensor. This is my first implementation of the device on nRF52 (not a module).

The device diameter is 44 mm.

On Board the device are:

• AM312 (PIR Sensor)
• BH1750FVI (Ambient Light Sensor)
• nRF52832
• Three-color led
• TPS61098x (Ultra-Low Quiescent Current Synchronous Boost with Integrated LDO/Load Switch - 300 nA)
• One 14250 battery (3.6v)
• SWD (micro)
• Two side buttons (first button-reset, the second button - interrupt (DIY)
• Power switch
• SWD adapter - gift.

Very long life on one battery.

What can this motion sensor do:

• Sending the status of the motion sensor to the controller
• Three modes of motion sensor (Night | Day | 24 hours)
• Adjustable soft delay (without delay | 1minute - 4 hours)
• Sending the remaining battery charge as a percentage
• Sending the illumination level in Luxs

Configuring via 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.
