Sun SPOTs in Rain forest!

THE RAIN FOREST!
The Sun SPOTS!
I had blogged about the project Canopee last time around. Me, and Vasusen Patil went for the complete requirement analysis and on-field prototype testing at the KMTR forest from January 8 - 13. We had a BLAST!!! Here I will present a short summary of our experience.
On January 8, we visited the ATREE head-office at Bangalore, and met Dr.T. Ganesan and Dr. Soubdra Devy. We gathered their requirements for sensors in the canopy. We were at the ATREE field station at KMTR from 9th to 12th. There, we interacted with Dr. T Ganesh who is leading the canopy research program on field. We studied the system of HOBO data-loggers that they have employed for monitoring temperature, light and humidity parameters in the canopy. We analyzed their mechanism of protecting the circuit from harsh weather conditions, and the reasons of failure of most data-loggers. We deployed the SPOT at one of their on-field monitoring sites to monitor temperature and light for 24 hours. Also, we tested the SPOTs extensively for wireless radio range in different conditions (varying in altitude, humidity, density, and vegetation).
Finally, we concluded that the range of the Sun SPOT is sufficient to send data wirelessly from the top of a tree to the ground in dense foliage. The readings for 24 hours that we obtained were also satisfactory and resembled closely the readings that the researches currently get using data-loggers. It was decided that a long-term deployment (about 2-4 months) of the SPOT in on-field conditions was necessary to conclude that the SPOTs could be used to design a system of wireless sensing at KMTR.
Coming up is a series of blogs that will highlight all details of various aspects of our visit including the Sun SPOT Range testing, The Rainforest experience, the Leech experience, the prototype testing results, and other ideas that came up during the visit.
So, stay tuned!
