Its a piezoelectric element (much like a microphone) and detects vibration and or bumps.

(simular to what you find in the back of a battery watch, that white patch that emits sound)


It listens for detonation (pinging/pinking ) and tells the ECU to retard the timing in steps if theres any evidence.
