Smart Solar LED Street Lamp (EE1111A)
Off-grid island street lamp: PV charging into a LiFePO4 battery, targeting at least 10 lux and two nights of autonomy. Arduino control with LDR-based PWM dimmin
Overview
- Off-grid island lamp: PV panel charging a LiFePO4 battery
- Targets: at least 10 lux and two nights of autonomy
- Arduino with LDR day/night sensing and PWM dimming
- Motion-triggered boost: PIR (final design), ultrasonic (prototype)
- DC-DC boost converter at 0.58 duty cycle
- Timed day/night switching prevents flicker
- Co-designed in a team of 6
