Multi-parametric environmental diagnostics and monitoring sensor node

A multi-parametric environmental diagnostics and monitoring sensor node, comprising:

• a base having opposed upper and lower faces and an opening formed therein;
• a plurality of environmental air quality sensors, each of the sensors having opposed upper and lower surfaces;
• a connector engaging each of the lower surfaces of the environmental sensors, wherein each of the connectors are mounted on at least one auxiliary harvesting module;
• a microcontroller mounted on the upper face of the base, the environmental air quality sensors being in communication with the microcontroller;
• a power storage module in communication with the environmental air quality sensors and the microcontroller;
• an external photovoltaic cell mounted within the base, the external photovoltaic cell being exposed through the opening in the base;
• a cover attached to the upper face of the base, the cover having an opening defined therein;
• the at least one auxiliary harvesting module in communication with the power storage module;
• an internal photovoltaic cell mounted on the cover, the internal photovoltaic cell being exposed through the opening in the cover;
• and
• a power management circuit connected to the power storage module, the power management circuit having a plurality of switches configured for selectively controlling communication between the power storage module and the external photovoltaic cell, the internal photovoltaic cell, and the at least one auxiliary harvesting module to charge the power storage module either separately or simultaneously from multiple sources, the internal and the external photovoltaic cells each being in communication with the power storage module for electrical charging thereof, the base being adapted for mounting on a support surface such that the external photovoltaic cell is selectively exposed to light from an external source and the internal photovoltaic cell is selectively exposed to light from an internal source.
