4. Measurement Range and FOV
TFmini measurement range
1) Indoor conditions:
The object to be detected has 90% reflectivity and the effective detection distance is 12m;
The object to be detected has 10% reflectivity and the effective detection distance is 5m;
2) Outdoor conditions:
Under the general sunshine condition (with illumination of lower than 70klux), the effective
detection distance is 7m;
Under the high sunshine condition in summer (with illumination of above 100klux) or the condition
with outdoor black background board, the effective detection distance is 3m.
Note: All distance parameters are set under the opposite direction with the object to be detected.
