The VDB1618 is a Bluetooth beacon with an accelerometer, temperature and humidity sensor. It uses a broadcasting protocol which is based on BLE (Bluetooth Low Energy ). VDB1618 broadcasts its general config parameters like UUID, Major, Minor, RSSI etc. to surroundings over the BLE channels 37, 38 and 39 continuously and non-directionally.
VDB1618 is based on Nordic Bluetooth 4.2 chip. It uses LIS2DH12 triaxial acceleration sensor and SH31 temperature and humidity sensor to realize the broadcasting of motion state and temperature and humidity information. It is powered by 2 ER14250 batteries. Its battery life is related to the internal broadcasting parameters.
