Simple parts, informed choices.
The aim is to use inexpensive, familiar hobby electronics available through electronics retailers and marketplaces such as Amazon. Exact models matter: wait for the verified parts list before purchasing for a Sentinel build. No particular listing or seller is endorsed here.
Technical platform, when you want the details
Sentinel Alarm’s current development platform is an ESP32 / T-Display board. That means a small programmable board with a built-in screen and wireless connectivity. Exact supported revisions, connections and software requirements are still to be documented.
Download center
No firmware, installers or release archives are published. There are no verified version numbers or checksums to list.
Future releases should include exact hardware requirements, a changelog, integrity checksums, license terms and known limitations. Until then, the Sentinel Alarm waitlist is the appropriate next step.
Sentinel Alarm development waitlistBefore attempting a build
Wait for revision-specific instructions. Do not infer electrical compatibility from a board or pump family name. Keep experimental equipment away from a live aquarium until its behavior and failure modes have been verified.
