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?
- 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
- 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
- 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.
- 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
