Sensor Board
About the Sensor Board
Sensor Board is an open source PCB design by CMGeldenhuys, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 68 × 38 mm, with 62 components from 23 distinct parts.
Other key parts include the TLV741PxxDBVx, OPA377xxDBVx and THS4551. By type, the board carries 21 resistors, 15 capacitors, 8 microphones, 3 ICs, 1 connector and 1 diode.
It belongs with the usb & debug tools, rf & radio and sensors designs in this gallery.
From the project
Spatially-Distributed Temporally-Synchronised Infrasonic Recorder
Kleinvoet is a self-contained low-cost passive acoustic monitoring device. The recorder was initially designed for distributed infrasonic (8Hz) localisation, and features accurate temporal synchronisation through the use of an onboard GNSS module.
The recorder is capable of 24-bit stereo recording at a variable sampling rate of 8kHz to 192kHz. The recordings along with timestamp and operational log information is stored on a microSD card. The recordings are stored as a series of 256MiB WAV files.
