Why can't my IR collision sensor work normally - the barrier indicator is on while there's no barrier in front?
- check if the barrier indicated light keeps on while there's no obstacle in front. If it is, please check if the IR sensors are getting too close or deforming, try to separate or straighten them slightly and check if the indicator still keeps on;
- try using a 2.5mm cross screwdriver to adjust the sensitivity regulator clockwise (Reduced sensitivity);
- if the above method doesn't work, try change the abnormal IR sensor to another one beside, to figure out the problem is from IR sensor or connecting port on mainboard. If the abnormal IR sensor still not good after changing the connecting port, it means the problem may occurred on the IR sensor, otherwise it may occured on the connecting port on mainboard;
