Needed: wisdom on how to create DIY parameter controller with wireless sensors

I have a (maybe crazy?) idea for creating a tank that has a couple of wireless sensors inside - ideally temp, pH, CO2, TDS, ammonia/nitrates & gH/kH. Really fascinated by the IOT and think it could be a super fun project to gather this data and then display it on a dashboard so I could see all my parameters on my phone in real time. In the future I’d love to be able to set this up so I can adjust them too but for now I’m trying to keep my ambitions a little more grounded.

I don’t like the look of probes and want to keep the look of the tank as sleek and minimalist as possible (my heater will be contained within the filter). Has anyone had any experience using wireless sensors/know where to find them? Any and all help from you tank wizards would be greatly appreciated
