Air Pressure Change Sensor
The FKS 111 sensor is a pressure sensor that can detect small fluctuations in air pressure. The change in pressure is detected by a piezo element and the electrical signal is amplifiered by a charge amplifier. The smallest detectable pressure change is 1 Pa, but higher pressure around 100 kPa is no problem for the sensor. The sensor does not react to sound.
