Question by PETER GALVIn | Product code: 35-0180

27th February 2012

QWould this be suitable as part of a Bat detector circuit? Bats emit Ultrasonic noises upto 99Khz but many are 25Khz - 60 Khz.

AThe bandwidth for this product is only 2KHz so in reality 38KHz to 42KHZ which is quite narrow for your purposes, I would also have doubts regarding its sensitivity to the level of reception from the bats. I'm afraid we can't offer anything which would be ideal for you.
