Small arduino (ATMEGA328p-MU) compatible and battery powered sentry node. It features a low power PIR presence detector (AM612), RGBW light sensor (VEML6040A3OG) and Temperature/Humidity sensor (HDC1080DMBT). Communication is provided by a RFM69 radio module. In addition, it also features a RGB LED behind the PIR lens for visual indications (if wanted).
It is powered by a AA size Lithium Thionyl Chloride battery with a capacity of 2600mAh (ER145053FP). This is enough capacity to power the device for >8 years, assuming an average reporting rate of once every minute. To preserve power, an external ultra-low power watchdog (TPL5010DDCT) is used for waking up the MCU at certain intervals if no presence is detected.
This board contains QFN packages and uses 0402 size components.
The zipfile contains the gerber files and a pdf with the current schematic, BOM, board assembly views, dimensions drawing, drill info, 3D model… Full documentation, firmware and 3D printable enclosure is still in development and not (yet) included.
