SOLAR POWERED SMART BLIND

  • WHAT - Self-sustaining, fully automatic blinds

  • WHY - Profitable market, convenient

  • WHO - Disabled, senior citizens, automation enthusiasts

  • COST - Competitive in prices with current products


Spsb system overview
SPSB System Overview

  • Energy efficiency using solar power

  • Blind will be fully automatic

  • Manual override can be performed by the user

  • Blinds auto adjust based on user input mode

  • LCD will display date, time, room temperature, and current user select mode

I 2 c communication
I2C Communication

  • Only two I/O ports

  • Bi-directional communication

  • Multiple slave devices


Light detection
Light Detection

  • Four photo-resistors

  • Pull-down resistor network

  • Sensitivity

    • VOUT (0V – 5V)


Stepper motor driver
Stepper Motor / Driver

  • Four wire bi-polar motor

  • Current range (150mA - 750mA)

  • Power supply range from 7V to 30V.

Demonstration plan
Demonstration Plan

  • Recorded video demo: recording of SPSB throughout a day

  • Live demo: user input modes and the blinds let light in accordingly


Problems and issues
Problems and Issues

  • Electrical

    Solar power might not be sufficient to power whole unit

    Solution: AC-DC power adaptor

  • Mechanical

    Stepper motor with driver might not provide enough torque

    Solution: Servo motor with feedback
