Summary Checklist for Low-Power Design

With these tips, power consumption can be cut significantly. Read about one case study where we extended the battery lifetime by 500%.

Wireless Transmission Checklist

  • How much data do you need to transmit? How far?
  • Which is the appropriate type of wireless transmission?
  • Is a gateway needed or will there be a direct connection to the Internet?
  • How often does it need to be on?

Display Checklist

  • Consider grayscale LCD or digital paper
  • Avoid or limit backlighting
  • Smaller displays take less power
  • Use sound or single LED for user interface
  • Send data to a phone for display

Sensor Checklist

  • Choose the appropriate type of sensor
  • Turn off sensors when possible
  • Leverage camera or GPS in cell phone if possible
  • Choose the appropriate sampling rate

Microprocessor Checklist

  • Select the right processor for the tasks
  • Minimize power hungry processing
  • Sleep whenever possible
  • Compressing takes processing power, but compressed data usually saves more on wireless transmission power, so compressing data before transmitting wirelessly is usually better.

Software Checklist

  • Power down subsystems when not being used
  • Dim the display when no input from the user
  • Use wireless connections efficiently
  • Transmit bursts of data
  • Do not sleep too long (cellular & WiFi need to re-establish connection)
  • Off-load energy-intensive processing to mobile applications or to the cloud
  • Use a motion sensor instead of GPS
  • Check that devices that are supposed to be powered down actually are off
