Kusamalira tsiku ndi tsiku kwa masensa amayamba ndikutsuka. Pukutani pamwamba pa sensor pafupipafupi ndi chotsukira chofatsa komanso nsalu yofewa kuti muchotse fumbi ndi dothi, onetsetsani kuti sensor ingathe kuzindikira komanso kuchuluka. Makamaka, oyeretsa amayenera kusankhidwa kuti asawonongeke kwa sensor chisindikizo ndi malumikizidwe amagetsi. Kwa masensa omwe amagwiritsidwa ntchito mu madera achinyontho, njira zoyenera zamadzi zimayenera kutengedwa, monga kugwiritsa ntchito zipolopolo zosayandama kapena zopangira madzi, kuteteza chinyezi kuti chisalowe mkati mwa sensor ndikukhudza momwe akugwirira ntchito. Kuphatikiza apo, mukamatha, chingwecho chiyenera kudutsa cholumikizira madzi kapena chitoliro chowunikira, ndikulimba nati, nati matemberero kuti muchepetse madzi amvula, etc.
