AI Overview
If you’re looking for a motion sensor to trigger audio from a speaker, the most direct options are motion-activated audio players (motion sensor + speaker/MP3 built in), or a standalone motion sensor module you wire into your own audio/speaker setup.
Motion-activated speaker / audio player (all-in-one)
- Recordable Audio Speaker Sound Box Built-in MP3 Player ($34.35) — a compact motion-triggered sound box with built-in audio playback.
- Motion Activated Audio Player with Separate PIR ($99.80) — PIR motion sensor triggers audio; separate PIR makes placement easier for installations.
- Motion Activated Audio Player with Two Separate PIR ($100.70) — similar, but supports two separate PIR sensors for wider/dual-zone triggering.
Motion sensor modules (to connect to an amp/speaker or controller)
- Mini PIR Motion Sensor ($5.35) — tiny PIR motion sensor module for simple motion-trigger builds.
- Arduino Compatible PIR Motion Detector Module ($7.20) — easy digital motion output for Arduino/microcontroller projects.
- Breadboard-friendly Mini PIR Motion Sensor with 3 Pin Header ($8.30) — compact 3-pin PIR for breadboards/prototyping.
- Mini PIR Sensor with Time and Sensitivity Control - BS612 ($4.15) — PIR with adjustable time + sensitivity.
Higher-end “presence” detection (better than PIR for stationary people)
- Fermion: C4002 mmWave Human Presence Sensor - Static & Motion Detection for Home Assistant (10m) ($21.90) — 24GHz mmWave presence sensor that can detect still occupants (useful for smart-audio/automation triggers).
- mmWave - C4001 24GHz Human Presence Detection Sensor (25 Meters, UART) ($25.75) — longer-range UART mmWave presence/motion sensing.
Do you want an all-in-one motion-activated speaker/audio player, or just a motion sensor module to trigger your existing speaker?
