In fifteen words or less, explain the significance of this contribution (Novel Aspect).: Power management system of high power components on small battery for extended remote sensor deployment

Abstract Text: Deployment of remote sensors for monitoring environmental and ecological trends often require long-term operation with battery power. A recent 4-channel fluorescence and Raman scattering system developed in our laboratory is constructed for a month-long emplacement on a dock at the Baruch Marine Field Laboratory in Georgetown, SC. It powers four Thorlabs avalanche photodiodes (APDs), a 450 nm laser source, an Arduino Nano 33 BLE Sense microcontroller with an SD card and a Raspberry Pi with Wi-Fi for an internet connection. In this poster we will describe the power consumption of each component of the system and the circuits and power scheduling strategy to enable the circuit to function for the entire period from a 90 A-hr battery.
