:bulb: **建議==兩周==為一個 SPRINT**
* 力求韌體整合進度即時更新且資訊透明，有助周例會討論，降低專案風險。

## 韌體整合計畫

### 需求

#### BLE Gas Level Sensor
* ==技術議題: nordic 為何無法連結 TNK Level Sensor?==
* 無法偵測到4公斤瓦斯桶，16公斤，失敗率高，目前只有20公斤比較好。
* 感測器廠商會再寄出兩件樣品，屆時持續驗證。
                                
| Item                            | Specs                              |
| --------------------------------|------------------------------------|
| Max measuring level range       | 1.5m                               | 
| Measuring error                 | ±1%FS(Full Scale)                  |
| Gas cylinder size               | 4kg to 50kg (steel, ~~aluminium~~) |
| Gas type                        | Liquid gas (propane, butane)       |
