BatEchoMon

Why in the news?   

           Recently, India’s First Automated Bat Monitoring and Detection System was created by the Indian Institute for Human Settlements (IIHS), Bengaluru.

What is BatEchoMon?

• BatEchoMon stands for “Bat Echolocation Monitoring”. It is India’s first automated, real-time bat monitoring and detection system.
• The system was developed by bat biologist Kadambari Deshpande and engineer Vedant Barje under the guidance of Jagdish Krishnaswamy.
• It was designed as part of the Long-Term Urban Ecological Observatory at the School of Environment and Sustainability, Indian Institute for Human Settlements (IIHS), Bengaluru.

What Does BatEchoMon Do?

• BatEchoMon autonomously detects, records, analyses, and classifies bat echolocation calls in real-time — something that previously took researchers months to do manually.
• It includes:
  • An ultrasonic microphone using a modified AudioMoth
  • A Raspberry Pi microprocessor to process and classify calls.
  • A solar-powered battery for power and a Wi-Fi unit for data transmission.
• The device activates automatically at sunset and continuously records audio through the night.
• It uses a Convolutional Neural Network (CNN) algorithm to distinguish bat calls from other sounds and to classify them based on peak frequency and call structure.
• The output includes:
  • Spectrograms (visual frequency-time plots of bat calls),
  • Audio files of bat calls,
  • Species-specific statistical data showing call frequency and timing
