3rd Party libraries / resources used:

Hardware:

• Many basic components (resistors, capacitors, etc) are from the SparkFun Eagle libraries
• LIS3DH accelerometer from SparkFun: https://github.com/sparkfun/SparkFun_LIS3DH_Arduino_Library
• Wisol Chip from hellogitty/WiSol (greatech.de) https://github.com/hellogitty/WiSOL

Software:

• LowPower library from RocketScream: https://github.com/rocketscream/Low-Power
• SparkFun LIS3DH library (https://github.com/PaulStoffregen/AltSoftSerial)
• Bosch BME280 library (https://github.com/PaulStoffregen/AltSoftSerial)

In eagle, set the directories for libraries to add the libary files included here if not already included, e.g. $EAGLEDIR/lbr:{PROJECT-DIR}/Libraries/SparkFun-Eagle-Libraries-master:{PROJECT-DIR}/Libraries/WiSOL-master/Eagle_Library

Plus use the New Library -> execute script to add the components in script form from the scripts dir
