Save Energy

The most important part of energy use in hospital buildings is to identify its usage patterns and maintain power supply even in blackout situations, rather than to save energy. This paper presents the power energy usage patterns of general hospitals as basic data for the establishment of countermeasures in blackout situations.

Sensing Time

IoT, a sensation in modern-day technology, has a major impact on the rapidly growing technological aspects. It’s making people’s life easier and also enabling us to do things that were previously seen as miracles. It helps in solving many complex real-time problems. One such major application in the field of agriculture can turn out to be productive and profitable. This paper explains a variety of techniques infusing IoT in agriculture, that helps in productive and predictive results in that field, thereby leading towards precision agriculture. A low-cost power supply and unambiguous farming can be possible with using IoT system. Wireless Sensor Networks (WSN) in which sensor nodes learn and adopt over the sensing time, gives simplicity, low energy usage. This is aimed to be deployed on a large scale by predicting using big data techniques from centralized data analysis.

Uninterruptible Power Supply (UPS) is increasingly becoming popular as a means of providing conditioned and uninterrupted power supply to sensitive and non-sensitive loads at critical and non-critical times.Sensitive modern equipment with very low tolerance for power fluctuation and failures are on the increase due to advancement in science and technology, theseequipment however require power backed up if they are to perform optimally. This study focuses on modification of the UPS in order to extend its running time.A used and dumped UPS working at a back-up time of between 0 to 10mins was modified to accommodate two, 75AH Lead acid batteries, using 1400VA Zinox UPS. An extended backup time of between 2hrs to 8hrs on the same UPS using Lead Acid/Deep Cycle batteries was achieved which at the same time operating within a very low budget.
