Sharp 2Y0A710K0F 100-500cm
Formel
Model: „100500“ [100cm to 500cm]
Based on the SHARP datasheet we can calculate the linear function:
y = 137500x + 1125 which gives us: 1 / ((Volt - 1125) / 137500) = distance_in_cm (For distance > 100cm)
Sharp 2Y0A21YK 10-80cm
Formel
Model: „1080“ [10cm to 80cm]
| Volt | Distance |
|---|---|
| 2,6 | 10 |
| 2,1 | 12 |
| 1,85 | 14 |
| 1,65 | 15 |
| 1,5 | 18 |
| 1,39 | 20 |
| 1,15 | 25 |
| 0,98 | 30 |
| 0,85 | 35 |
| 0,75 | 40 |
| 0,67 | 45 |
| 0,61 | 50 |
| 0,59 | 55 |
| 0,55 | 60 |
| 0,5 | 65 |
| 0,48 | 70 |
| 0,45 | 75 |
| 0,42 | 80 |
Using MS Excel, we can calculate function (For distance > 10cm) :
Distance = 29.988 X POW(Volt , -1.173)
