Welcome @gagandeep.jindal – I haven’t heard of anyone doing an AquaTroll sonde before but it looks like it can communicate over RS485 and SDI12.
For SDI12, we have one person working on an integration on the forum here: BM Sensor Integration - SDI-12 Multiparameter Sonde EXO3s - #2 by umakat.
For RS485, we have another group working on an integration on the forum here: Integrating an RS-485 device (Rx-LIVE acoustic animal tag receiver) with Bristlemouth - #7 by estackpole.
Neither are 100% turnkey right now but with a little firmware experience I believe either path to be do-able.
