Smoke alarm false alarms - inspection needed

My smoke alarm has recently started triggering false alarms at random times, even though there are no signs of smoke or fire. I'm unsure what's causing the issue, so I need someone to: 1. Inspect the smoke alarm to figure out what’s wrong. 2. Fix the issue or perform any maintenance needed to stop the false alarms Photos of the alarm are attached for reference. Since the exact cause isn’t clear, it would be great if you could bring any basic tools you might need to avoid extra trips. Thanks in advance for your help.
