1. A method for power management for a retrofit sensor system for a vehicle, the method comprising:
- at a control center attached to the vehicle, determining a driving state, the driving state predictive of a driving event;
in response to determining the driving state, at the control center, wirelessly transmitting a first command to operate in a mid-power mode to a sensor module attached to the vehicle, the sensor module comprising;
a sensor, an energy storage module, an energy harvester, and a wireless communication module;
in response to receiving the first command, at the sensor module, operating the wireless communication module in a mid-power communication mode;
at the control center, receiving a trigger from the vehicle;
in response to receiving the trigger, at the control center, wirelessly transmitting a second command to the sensor module to operate in a high-power mode;
in response to wirelessly transmitting the second command, at the sensor module;
operating the sensor in a high-power sensor mode, comprising sampling a data set;
operating the wireless communication module in a high-power communication mode, the high-power communication mode comprising transmitting data above a threshold data transfer rate; and
transmitting the data set to the control center while operating in the high-power communication mode;
at the control center, wirelessly transmitting the data set to a user device within the vehicle;
after wirelessly transmitting the data set to the user device, at the control center, wirelessly transmitting a third command to the sensor module to operate in a low-power mode; and
in response to receiving the third command, at the sensor module;
operating the sensor in a low-power sensor mode; and
operating the wireless communication module in a low-power communication mode comprising transmitting data below the threshold data transfer rate.
