  In the 21st century, sending babies or children to daycare centres has become
more and more common among young guardians. The balance between full-time work
and child care is increasingly challenging nowadays. In Malaysia, thousands of
child abuse cases have been reported from babysitting centres every year, which
indeed triggers the anxiety and stress of the guardians. Hence, this paper
proposes to construct a remote baby surveillance system with radio-frequency
identification (RFID) and global positioning system (GPS) tracking. With the
incorporation of the Internet of Things (IoT), a sensor-based microcontroller
is used to detect the conditions of the baby as well as the surrounding
environment and then display the real-time data as well as notifications to
alert the guardians via a mobile application. These conditions include the
crying and waking of the baby, as well as temperature, the mattress's wetness,
and moving objects around the baby. In addition, RFID and GPS location tracking
are implemented to ensure the safety of the baby, while white noise is used to
increase the comfort of the baby. In the end, a prototype has been successfully
developed for functionality and reliability testing. Several experiments have
been conducted to measure the efficiency of the mattress's wetness detection,
the RFID transmission range, the frequency spectrum of white noise, and also
the output power of the solar panel. The proposed system is expected to assist
guardians in ensuring the safety and comfort of their babies remotely, as well
as prevent any occurrence of child abuse.
