Abstract. A hardware-software solution development of a low-power consumption acoustic sensor included into a wireless sensor network based on ultrawideband chaotic radio pulses is considered in the article. Low power consumption of the sensor is provided by power efficient electronic components and a new compressing method PADPCM, which is resistant to data block losses during packet transmissions within sensor networks.

Keywords: ultrawideband, chaotic, radio pulse, acoustic, sensor, compressing, packet transmission.
