The paper represents an accurate and economic low range (up to 5 A) ac current sensing scheme using high precision ACS712 hall-sensor. ATmega microcontroller is used in processing signal and for ...

As temperatures rise and the summer heat intensifies, air conditioners across the region are working overtime.

Air-conditioned (AC) water comes from a process called “condensation.” This happens when air passes the cold evaporator coils, and the water vapour condenses into a liquid form. This water becomes ...

If you don't have air conditioning or your AC is broken, use this alternative method to keep your home's temperature bearable ...

Advanced HVAC technologies are supporting the A2L refrigerant transition by improving system efficiency, safety, and ...

Simulations revealed that the annual energy-saving efficiency of the CV-ASHP system is 12.00%, the VC-ASHP system is 13.11% and the VV-ASHP system is 24.13%. The energy-saving efficiency of the ...

Joby Scarff, product manager, Arqiva Joby has developed a highly flexible managed service designed to support a wide range of water sensor devices and connectivity protocols.

In this paper, we describe the synthesis and characterization of analytical properties of fluorescence-based zinc ion-sensing glass slides and their application in monitoring zinc ion release from ...

A team at the University of Colorado Boulder is testing a new type of water sensor in Boulder Creek that is helping to monitor drinking and recreational water quality in Colorado and around the world.

But investigations and real-world accounts show that most resellers sell the water for far less—typically between ₦150 and ₦200 per jerrycan. Profits are minimal because a single AC unit only produces ...

Three-phase current measurement using only a single current sensor in the inverter dc link is appealing for ac motor drives because it minimizes the number of current sensors, thereby reducing sensor ...
