The Ultramic384K is a high quality, professional digital device that can work as:
The Bluetooth connection is used only for an easy configuration of the microphone if used as autonomous recorder. The ultrasonic transfer is done via USB.
The Ultramic384K BLE has an integrated analog-to-digital converter able to achieve a 384 kHz data sampling rate. The USB 2.0 full speed port allows an easy connection to a PC, iOS, Android smartphone or tablet and embedded Linux systems. The Ultramic384K BLE is composed of a main body with digital and differential analog amplification, a waterproof, high performance audio and ultrasonic microphone with a FG sensor, and a preamplification circuit. The ultrasonic sensor can be replaced with other sensors such as an infrasonic microphone, a vibration sensor, or a hydrophone. When used with an external USB battery, the Ultramic384K BLE's low power, integrated 32 bit microcontroller makes it the perfect device for long term autonomous recording.
The Ultramic384K BLE can be used in scientific research for: Bioacoustics and Industrial research:
