Enabling Wake-Up from Deep Sleep on Jetson Nano with LIDAR Sensor

Hello Jetson Community!

I’m currently working on a project involving the NVIDIA Jetson Nano Developer Kit, and I’m seeking guidance on implementing a wake-up mechanism from deep sleep based on LIDAR sensor readings.

Objective: I want the Jetson Nano to enter a deep sleep state to conserve power and then wake up when a LIDAR sensor detects an object within 50 feet.

Questions:

  1. What is the best way to put the Jetson into a deep sleep state?
  2. How can I configure the GPIO pin to act as a wake-up source from deep sleep?
  3. Are there specific GPIO pins that support wake-up capabilities?
  4. What are the considerations for integrating an external wake-up source like a LIDAR sensor?

Additional Information:

  • I’ve reviewed the Jetson Nano documentation and forums but would appreciate more specific guidance on GPIO wake-up configurations.
  • The goal is to optimize power consumption by allowing the Jetson Nano to enter deep sleep and only wake up when needed.

Any insights, advice, or examples from the community would be greatly appreciated. I’m open to suggestions and eager to learn from your experiences.

Thank you in advance for your time and assistance!

Check below for suspend the system.

Your case need LIDAR device have interrupt pin to connect to Nano GPIO to wake up the system.
