| 3 | 4 soil moisture Sensors can be connected to the board. |
||
| 4 | The sensors can be evaluated one after the other. |
||
| 5 | |||
| 6 | With shrinking hose on the sensors, the values look quite stable. |
||
| 7 | Each sensor needs it calibration according to the type and cable. |
||
| 8 | 3 | Maximilian Seesslen | Air- and Water-Values are needed. |
| 9 | The reported value is promil; 0=Air and 1000=Water |
||
| 10 | 1 | Maximilian Seesslen | |
| 11 | In raw mode, values are send in Hz, in normal mode, its send as permil. |
||
| 12 | 6 | Maximilian Seesslen | Cordyceps should also plot raw values in order to see if values are stable. |
| 13 | Change mode automatically? only show Hz in a field. |

| 15 | 1 | Maximilian Seesslen | TDT-Commands: |
| 16 | 2 | Maximilian Seesslen | * Raw |
| 17 | * Calibrate dry |
||
| 18 | 1 | Maximilian Seesslen | * Calibrate water |
| 19 | * change sensor |
||
| 20 | 6 | Maximilian Seesslen | |
| 21 | Calibration procedure: |
||
| 22 | * set to calibration via command |
||
| 23 | * Calibrate dry via command |
||
| 24 | * Calibrate water via command |
||
| 25 | * Reset via command |
||
| 26 | 7 | Maximilian Seesslen | * Temperature? check warm water |

| 28 | Measuring time |
||
| 29 | |||
| 30 | 9 | Maximilian Seesslen | Measure over a long time may remove noise and smoothen the values. |
| 31 | 1 | Maximilian Seesslen | But too much noise will already provide wrong measurements. |
| 32 | 9 | Maximilian Seesslen | So the time should be small. Hardware noise should be detected. |
| 33 | |||
| 34 | This was already done long time ago. |
||
| 35 | |||
| 36 | Just connecting Mainswitch near sensemux does help a lot reducing the noise. |
||
| 37 | So ferritbeat may not help but there are already. |
