Development of a wireless sensor network based smart multiple ambient conditions sensing system for the rearing process of eri silkworm

Abstract

Assam has a strong contribution in the world silk production. Several rural families of this region are engaged in this activity. Socioeconomic development of this region is also dependent on these activities. This paper presents a wireless sensor network-based instrumentation to record the process conditions of the rearing process of eri silkworm, which canfurther help to optimize the rearing process. For this purpose, temperature, relative humidity, light intensity takes as major process parameters on which the rearing process depends. These parameters are recorded using sensor BME 280 for temperature & relative humidity and BH1750 for light intensity which is interfaced with an ATmega328/P microcontroller. This works as a sensor node and three sensor nodes are required for complete monitoring of the rearing process. Wireless sensor network is utilized for interconnecting each sensor node through a master node which obeys star topology. The system is then tested in the laboratory and compared with the standard equipment. The system is installed in the rearing process for data collection. The collected data are further analyzed for its daily variations.

Utilization of huffman coding for weather buoy system using long-range communication

“…It only serves as a learning material for compression and decompression techniques of Huffman Coding [14]. The use of Huffman Coding for data transmission proves its high efficiency in this study, however the project does not support real-time simultaneous data collection, which is not ideal for weather monitoring buoys [19].…”

“…The most significant parameters in WSN concerned for CH selection are energy, delay and distance [13]. Doloi et al [14] used CC2500 Radio Frequency (RF) modem as a transceiver module which is a straightforward communication at 2.4 GHz, and a short distance module which is not a problem for this study doesn't require long range. It also used star topology, and the difference is the data gathered is not sizable enough to cause slower transmission, thus doesn't require digital signal processing.…”

“…The application of Huffman Coding in Julia Language can be easily navigated and understood by the users [14]. The benefits of applying Huffman Coding in a Data Acquisition (DAQ) system are low power consumption, the high effectivity rate of transmission, and shortens the processing time [19].…”

Performance of Bombyx mori and Samia cynthia ricini silkworms under controlled environmental conditions in Uasin Gishu County

“…Pakhale et al (2014) [14] study in India and Singh et al (2002) [21] reported longer larval duration of 29±3 days, which they attributed to differences in temperature and humidity, which could explain the results reported in the current study. The ideal temperature range for Eri worm rearing is between 20 o C and 35 o C and an increase in temperature beyond that causes less spinning and mortality in larvae (Doloi et al 2019) [3] the reason why Eri worms did not survive to 5 th instar, in L6 and L7 could be due to these conditions.…”
