IoT-Based Automatic Home Light Monitoring System Using Wemos D1 Mini

August 2022 · Journal of Technomaterials Physics

This research aims to design an IoT-based home light monitoring system using Wemos D1 Mini. This tool is designed to control the current and voltage contained in house lights automatically. The sensor used to measure the current in the house lights is the ACS712 sensor, and the sensor used to measure the voltage in the house lights is the ZMPT101B sensor. The simulation of the house lights on ... [Show full abstract] this tool uses three LED lights, where each lamp is located on the terrace of the house, living room, and kitchen with different light power variations. In addition, the Blynk application on smartphones can be used to turn lights off and on and monitor currents and voltages. The test results show that this tool can control three regulated room lights and monitor the current and voltage in the three lights online using the Blynk application.

EQTT: An energy-saving and quality-guaranteed target tracking mechanism for WSNs

May 2014

Target Tracking is one of the most important issues in wireless sensor networks. In a densely deployed wireless sensor networks (WSNs), all sensors participating in the monitoring task can provide full coverage but might inefficiently consume their energies if the target did not enter the region. This paper proposes an energy-saving and quality-guaranteed target tracking mechanism, called EQTT, ... [Show full abstract] which dynamically wakes up sensors in a distributed manner, aiming to minimize the number of working sensors while the user-defined tracking quality can be satisfied. The proposed EQTT mainly consists of two phases: the network initialization phase and target tracking phase. The first phase aims to wake up minimal number of boundary sensors whose sensing range is intersected with the boundary of the monitoring region M. These working sensors can construct barrier coverage for the boundaries of M and all the other sensors stay in sleep state for energy conservation. When the target is detected by the boundary sensors, the target tracking phase is automatically initiated, which aims to further wake up minimal number of neighboring sensors of the detected sensor but satisfy the user-defined tracking quality.

Development of Low-Cost Compact Omnidirectional Vision Sensors

January 2001

H. Ishiguro

Physical agents living in complex environments, such as humans and animals, need two types of visual sensing abilities. One is to focus on particular objects with a precise but small retina, the other is to look around the environment with a wide but coarse retina. Both visual sensing mechanisms are required to enable robust and flexible visual behaviors. In particular, the omnidirectional visual ...

December 1996

This paper presents the BIFEST, an ATPG system that combines the conventional ATPG process and the built-in intermediate voltage test technique to deal with CMOS bridging faults. A PODEM-like, PPSFP-based ATPG process that can effectively and efficiently model the bridging fault effects is developed to process those faults that are conventionally logic-testable. The remaining faults are then ... [Show full abstract] dealt with by special circuits called built-in intermediate voltage sensors. By this methodology almost the same fault coverage as that employing IDDQ testing can be achieved with only logic monitoring required

Power characteristic analysis method of optical remote sensor based on command sets

May 2014

For monitoring the work states of optical remote sensor in real time and automatically alarming when the work states are abnormal, the power characteristic analysis method based on command sets of optical remote sensor was developed. By sampling and iterating the relationship between power and various command sets, the dynamic threshold function based on command sets was summarized. And the ... [Show full abstract] threshold function was optimized, since some actual conditions must be considered such as surge, command delay and so on. And the optimized threshold function was applied to the power monitor and control system. The system adopted 20 Hz sample frequency to monitor the power of optical remote sensor in the heat cycle experiment, which would last 12.5 days. The command refresh cycle was 512 ms of the optical remote sensor. The results show the method can exactly monitor states of optical sensor and alarm when the states are abnormal. That puts power alarm method of optical remote sensor into practice and has great value to tester.
