Product Details

Introducing the PiPistrelle version 5.3 a handheld bat detector that offers advanced features for detecting and analysing bat calls. With Heterodyne dection and automatic scanning, this device preserves the rhythm and harmonic relationships of bat calls without the need for manual tunning! This allows for effortless 'eyes to the skies' operation.

The PiPistrelle also features an advanced "Time Expansion" mode, which slows down bat calls by 16x or 10x, giving users the ability to reveal the true nature of bat sounds. This innovative device comes equipped with an audio output over a headphone socket, allowing users to listen to bat calls in real-time.

Additionally, the detector can be connected to an external powered speaker to lead bat walks and share the experience with larger groups.Featuring a 10-LED real-time spectrum display, the PiPistrelle indicates the approximate frequency of calling bats, providing valuable insights into their behavior.

What's more, users can access more detailed information via frequency speech synthesis, enhancing their understanding of bat communication. With all the Pippyg static bat detection and recording features, this handheld detector is a must-have for anyone passionate about bats and wildlife.

    • File size optimised for analysis by BTO Acoustic Pipeline
    • Files timestamped and location-stamped
    • Geolocation metadata stored in industry-standard "GUANO" format
    • iOS / MacOS / Android app configures device for recording
  • Devices typically run for 4 to 7 days
    • Quoted times are based on measured performance using 2450mAh rechargeables
    • Actual run-time depends on how many recordings are triggered
    • Writing to microSD is the most power-hungry operation
    • Battery life is longer when fewer recordings are made
    • Selection of trigger level and sleep/wake times are important
  • Heterodyne detection
    • Rhythm of bat calls is preserved
    • Scans automatically for bat calls
    • No manual tuning - "eyes to the skies" operation
  • Advanced "Time Expansion" mode reveals true nature of bat sounds
    • Harmonic relationships of bat calls are preserved
    • Slows down bat calls 16x or 10x (user-configurable)
  • Audio output over headphone socket
    • Connect to external powered speaker to lead bat walks
  • 10-LED real-time spectrum display
    • indicates approximate frequency of calling bats
    • More detail available via frequency speech synthesis

pippyg and π•pistrelle both powered by 3 AA batteries

pippyg and π•pistrelle run identical firmware

  • Configurable and upgradeable
    • Programmable "recording trigger" sensitivity
    • Programmable "awake CPU MHz" to burn less current when scanning for bat calls


Suite of support tools provided both as C++ source code and as precompiled cross-platform binaries

  • Binaries are .js for running in Node.js®, which is available for Microsoft, Apple and Linux
  • sonogram.js creates .jpg sonograms from recordings
  • chirpwav.js creates .wav file to configure devices
  • patchpip.js modifies firmware images to support device re-flashing with custom behaviour
