Ultrasonic Sensor-Based Automated Water Dam Shutter

Abstract

Monitoring the level of water in dams is necessary to ensure optimal operation and safety. Water level monitoring is normally done manually by a full-time operator. This results mostly in a waste of water due to the inability of the operator to accurately determine the quantity of water to release from the dam gate. The aim of this paper is to present the design of a system to automatically open and close dam gates based on the level of water in the dam. The system is based on a low-cost microcontroller and an ultrasonic sensor to read water level in the dam. SMS messages are sent to nearby residents to warn them of the opening of the dam gate. An alarm is also sounds before the eventual opening of the dam gate.

A Working Prototype Using DS18B20 Temperature Sensor and Arduino for Health Monitoring

“…Benjamin Kommey et al [6] proposed a patient medical emergency alert system (PMEAS). It uses two sensors: temperature sensor and heart rate sensor as a hardware unit and android application.…”

“…It has many potential applications to give rise to healthcare applications like remote health monitoring, a fitness program for home-based health-monitoring, chronic disease detection, and older people care, etc. IoT based healthcare service utilizes wireless body area network (WBAN) [6][7][8] which is a subset of wireless sensor network (WSN) [9,10]. Usage of WBAN in healthcare increases the QoS and reduces the costs with enhanced usability.…”

“…Usage of WBAN in healthcare increases the QoS and reduces the costs with enhanced usability. Initially, IoT based WBANs [6,7,11] are one of the most desirable technology for building smart health monitoring for the patient. The application of healthcare monitoring using WBAN consists of a specified number of heterogeneous sensor nodes.…”

“…With the help of WBAN, a user can be monitored at anytime, anywhere, and for any duration. In the WBAN-Based health-monitoring architecture is three-layer architecture [6,7,14,15] shown in Fig. 1 [3,5,6].…”

“…In the WBAN-Based health-monitoring architecture is three-layer architecture [6,7,14,15] shown in Fig. 1 [3,5,6]. Tier 1: enclose a set of small, smart sensors that are wearable or implanted in the human or patient body.…”
