This is a board that can capture and record specific sound waves for up to 36 hours.
The "Data Recording Board" is a board that can capture and record specific sound waves for up to 36 hours. The A/D converted specific sound wave data is recorded on an SD card and can be checked on a Windows personal computer. The current model is designed for a frequency of 500Hz, but it can be adjusted to the frequency range requested by the customer (customization costs are subject to separate consultation). Additionally, it is designed to be battery-operated, so it is equipped with a function that automatically stops data acquisition when the battery voltage drops. 【Features】 ○ A board that can capture and record specific sound waves for up to 36 hours → The current model is designed for 500Hz, and it can be adjusted to the desired frequency range ○ Sampling times can be set within the range of 100 seconds, 150 seconds, 200 seconds, and 300 seconds → An interval time of 20 seconds is required for writing to the SD card after each sampling completion ○ Verified operation with a 16.8V 2.2Ah lithium-ion battery (battery protection function) For more details, please contact us or download the catalog.
