REAL-TIME FLOOD MONITORING DEVICE USING TRUNCATED CONICAL CASING AND IR SENSOR WITH REFLECTOR BUOY

Abstract

Current flood monitoring device uses ultrasonic ranging sensors to detect water level.
Oftentimes, false reading is encountered due to stacked debris. Also, these designs are prone to tampering
because these sensors are exposed outside. The main focus of study is to provide real-time information to
flood prone area. The designed prototype will ensure the elimination of false reading due to the path
blocking of the washout debris under the ultrasonic ranging sensor and to ensure the device is tampered
proof. This will help local government units to immediately respond in times of flood disaster. The system is
capable of measuring the water level using infrared light enclosed in a cylindrical tube with reflective buoy.
The system used satellite to sense its location and transmit data using cellular communication. Flood
information is collected thru a database server and displays the status using web application. This will also
determine the ingress protection, accuracy and thermal performance of the system. The test results shows
the accuracy of eliminating false reading was 99.36% given the different mean size of debris. Also, the
device has passed the IP69 standard using ISO 20653 test procedure to determine the degree of ingress
protection of electronic enclosures. Furthermore, the device casing was able to dissipate the heat inside and
the maximum temperature was 36 degrees as shown by the thermal simulation.
