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

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 can further 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.
