Ultrasound - Part 2

It's been a little while since the original Ultrasound - Part 1 post. At that stage we were looking into different ways to capture the ultrasound that the bats are creating and we mentioned we would be putting up a Part 2 to show which option we went with.

We know that our bat detector must be as lightweight and small as possible and fortunately we were contacted a number of months ago by a chap called Peter from a company called Peersonic. Peter and his team are the designers and manufacturers of a fantastic detector called the RPA2. Check it out below:

The functions that the RPA2 provide are unparalleled at this price point. Add into the equation that we can just use the circuit board, which lives inside the housing in the photo, and you have a very lightweight (circa 100g) and small system which suits us perfectly.

It's worth adding that Peter and his team at Peersonic have been fantastic and are still supporting us in our efforts. Peter has configured a RPA2 to work with a load of batteries we have lying around (1S LiPo) and built us a number of bespoke microphones which discriminate against lower frequencies in order to reduce the engine noise saturating the bat calls.

We can't recommend Peersonic enough and if you'd like to check them out for yourself then we would highly recommend visiting their website at peersonic.co.uk.
