"Optimize Power Consumption for Battery-Operated Systems"

Improve the system's power efficiency, making it suitable for battery-operated or off-grid vehicles.

Steps to Complete:

Implement deep sleep mode for the ESP32 to reduce power usage during idle times.
Optimize sensor polling intervals to conserve power.
Evaluate alternative low-power sensors.
Expected Outcome:

A more power-efficient system for long-term use in vehicles with limited battery resources.

Start by locating the ESP32 idle and sensor-polling entry points, then review how the DHT22, MPU6050, and SW420 sensors are read. Implement deep sleep, adjust polling intervals, and assess low-power sensor alternatives; done means reduced power usage suitable for long-term vehicle operation.
