Optimizing Power Consumption for Solar Powered Rechargeable Lithium Ion (Li-ion) Battery Operated IoT Based Sensor Node Using WeMos D1 Mini

摘要

This paper propose an idea and implementation of the power optimization for the solar operated IoT sensor node for the data uploading on cloud. We have used Wemos D1 Mini board for the data recording, uploading data on cloud and power consumption optimization. The whole system is working on rechargeable 4000 mAh Li-ion battery which is charging through TP 4056 Charging Board. We have used BME280 sensor. The BME280 is a combined digital humidity, pressure and temperature sensor, we have sensed only humidity and temperature. For charging the battery we have used mini solar panel. The system is fully autonomous and working on solar power only. We have prepared one casing for the system so that all the circuit and components can placed inside the case for environmental protection.
