Centers For Disease Control and Prevention (CDC) light traps were modified for use with light-emitting diodes (LED) and compared against a control trap (incandescent light) to determine the effectiveness of blue, green, and red lights against standard incandescent light routinely used for sand fly surveillance. Light traps were baited with dry ice and rotated through a 4 x 4 Latin square design...

Perovskite solar cells (PVSC) have drawn increasing attention due to their high photovoltaic performance and low-cost fabrication with solution processability. A variety of methods been developed make uniform dense perovskite thin films, which play a critical role on device performance. Herein, we demonstrate polymer additive assisted approach Polyamidoamine (PAMAM) dendrimers facilitate the gr...

Microcontroller is a functional computer system on chip. It contains processor core, memory, and input output equipment. chip that used to control electronic One of the uses microcontroller embed it in chicken incubator egg incubator. An device heated by electricity at certain temperature incubate eggs, microbes warm babies who are born prematurely. In there lamp eggs so can hatch with good qua...

The population of the world has been increasing gradually in recent times. Under excessive climatic conditions, plants can be grown with help Greenhouse. Green houses to maintain temperature within a limited range, used for cultivating out season. greenhouse control system is powered by ESP-WROOM 32 Wi-Fi Microcontroller and it consists humidity sensor, soil moisture PIR sensor MQ Gas monitor I...

This paper presents the design of a light chamber which can be used to investigate the flicker behaviour of various types of lamps. Using this system, a lamp can be subjected to a controlled voltage waveform while current and illuminance of the lamp are monitored. With the aid of such a voltage source capable of generating voltage fluctuations, including interharmonics and other power quality d...

Voltage variation is one of lamps flickering main cause; thus evaluation of a disturbing light flicker is a part of voltage quality classification. The instrument for flicker level measurement by means of voltage variation analysis is named flickermeter and is specified in standard EN 610004-15. The flickermeter is a specialized analyzer modeling response of a chain consisting of reference 60W ...
