| Summary: | This project aims to improve the sustainability of Internet of Things through recycling
light energy used in indoor environments. It consist of an indoor solar-powered, Open-
Source Microcontroller with In-Built WiFi functions, powering a Humidity and
Temperature sensor, designed to transmit collected data to a nearby database or
monitoring device for environmental tracking of an indoor air-conditioned room. The
experiments of this project would prove that harvesting indoor energy and deploying
a self-sustainable IoT network is possible and viable for wide industrial applications.
Experiments are conducted under standard testing conditions to simulate an actual
indoor environment and the energy consumption of the setup is measured while
operating under a deploy-and-forget mode. Data collected are recorded in a cloud
server through an Application Programming Interface, Thingspeak. The circuit design
consist of an array Amorphous Silicon Solar Cells, a set of ‘AA’ Nickel Metal Hydride
Batteries, a DC-DC Buck Converter, a Humidity and Temperature sensor and a newly
launched IoT-specific Microcontroller board called Arduino MKR1000. The
Microcontroller possess impressive communication capabilities while consuming very
low power as compared to many commercial products in the market. In addition,
different types of Solar Cells and Battery Storages are accessed through IV Curve
performance parameters and power generation capabilities to select the best
performing and sustainable option under indoor conditions. Implementations and
results for this project will be included to display the effectiveness, reliability and
sustainability of this IoT sensor circuit as compared to existing technologies and
projects within the industry. |
