1.3 About CAREU U1 Lite(WR)
The CAREU U1 Lite(WR) vehicle tracker transmits the wireless signals such as location,
peripheral and vehicle control data to a control center. The onboard GPS receiver provides
users with location data including speed, direction, mileage and altitude. It uses an onboard
GSM/GPRS module to accomplish wireless transmission.
A microcontroller can probe location and command data at regular intervals, derive actions
from location, peripheral and control data, and execute such actions. Among the best
features of the CAREU U1 Lite(WR) vehicle tracker, in particular, they transmit data in
ASCII mode or binary mode. Peripheral data indicates the status of various peripherals
connected to and/or controlled by the device. The peripherals include, but not limited to,
door locks/un- locks, starter interrupt, ignition, battery, engine and panic button.
The firmware in the device applies intelligent filtering to overcome coverage limitations
for both GPS and GSM/GPRS networks. Motion sensor controls the status of the device,
whether in sleep, idle or fully-powered mode, and thereby controls the amount of current
