PS: by "Predict the energy level of battery operated sensor node", I want to mean that I am willing to predict the amount of energy the sensor node will have at a given point of time. In other words, I am interested in building some regression model for time series forecasting of the amount of energy a sensor's battery will have over the next few hours/days.
The parameters which I could thought of are as follows.
1. L_volt and H_volt of battery
2. L_curr and H_curr in the circuit
3. Energy consumption rate
4. Ambient humidity, temperature and altitude
5. Battery discharge Cycle.
6. Magnitude of solar panel's, LUX, current and voltage .
Please let me know some other parameters, which I can add to the above list.
I thank you all in advance.
I am not sure what you mean by 'predict the energy level'. Do you mean the sensor power consumption? If so, it will depend entirely on its electronic design, and if the applied voltage is not stabilised then on that applied voltage. I don't see that any of the other factors determine the load, which is what you seem to be asking. Am I missing something?
Thank you Prof. Tony Maine. I have now updated the question for better understanding.
If You use PV-panel, You needs take in to the account the cloudiness and it long time variations. Because cloudiness is decrise power near ten times. Long cloudiness interval can discharge any battery.
