Wi-Fi Marine Hour Meter
Budget: $30 – $250 USD
I need a compact, battery-powered hour meter that bolts onto a piece of marine equipment, connects to the boat’s Wi-Fi, and silently counts every minute the engine runs. Beyond simple hour logging, it must also sample and report its own battery voltage so I can tell when the internal cell is getting low.
The device should push both data points—total run-time and current battery level—to a cloud endpoint I’ll expose. I plan to read everything from a web-based remote dashboard, so no on-device screen is required. An LED or brief buzzer chirp during initial pairing is fine, but the unit will spend most of its life sealed in a damp engine bay. Reliability and low standby draw are therefore critical.
Please deliver:
• Hardware schematic and bill of materials for readily available components (must be available in Qatar!!!)
• Firmware I will complete myself, but for the prove of concept, the designer must show it works
• A short setup guide so I can flash, seal, and mount the unit without specialised lab gear
NOTE: this will be the first of many projects, so the lower the bids the more opportunities you will have to work with me in the future.
