<title>Optical power and irradiance microprocessor meter for fiber optic sensors and networks testing</title>

1999

In this paper are presented the optical power and irradiance meter with `an intelligent opto sensor' and the microprocessor measurement system. A designed and programmed microprocessor unit allows to measure a light power from 1 nW to 2 mW and an irradiance of light from 50 nW/cm2 to 150 mW/cm2 (with accuracy 0.2%) including sensor's and spectral responsively characteristic. It's built for measuring fiber optic systems, mainly for examination and testing of the optoelectronic sensor's structure (relatively small surface of the light detectors comparing to the partition of measured value) and it's an ideal detector for the fiber optic sensors and networks.© (1999) COPYRIGHT SPIE--The Interna…

A Novel Wireless Sensor Network for Electric Power Metering

2015

Wireless sensor network with lightweight and efficient communication infrastructures are today a great interest, both at research and industrial level, as they are the basis for reliable monitoring services. Mesh networks are ideal candidates in this scenario, as they can be very fault-tolerant. After introducing wireless network systems requirements, we show the design of a mesh network routing protocol based on AODV schemas. Its implementation runs on top of low-cost off-the-shelf components, and allowed us to build a custom power meter wireless sensor node.

Smart Plugs for smarter cities

Load control in modern power grids is becoming more and more important. Recently, energy monitoring and load control has gained interest from several actors such as energy utilities, and Demand Response mechanisms allow consumers to respond to signals from energy suppliers in order to reduce their energy consumption during critical periods, in exchange of discounts on electricity bills. Direct Load Control mechanisms allow energy suppliers, through the adoption of Smart Plugs, to automate load switch-o during such periods. These mechanisms have been traditionally applied to industrial customers only, leaving a major part of loads in the grid, e.g. household appliances, uncontrolled. Commerc…
