Kei roto i te pōro katote kino ngā irahiko pai me ngā irahiko kino. Kia pā atu ki te wai, ka taea e ia te tuku i te iahiko ki roto i te wai i taua wā tonu. Ko tēnei iahiko te iahiko 0.06MA tino pai mō te tinana tangata. Ina pā te wai ki te iahiko ngoikore, ka wehea ngā irahiko hauwai me ngā irahiko hāora i roto i ngā ngota wai e karapoti ana. I tētahi taha, ka honoa ngā irahiko hauwai ki ngā irahiko hei hanga hauwai, ā, ka honoa ngā irahiko hauwai hāora ki ngā ngota wai e karapoti ana hei hanga i ngā matū hohe, ā, ka whakaputa i te neke atu i te 300 ngā wā o ngā irahiko kino.

Āhuatanga
Ka taea e te pōro katote kino te tuku i te tini o ngā katote kino katote, ā, he tino hira te mahi whakaputa hiko pyroelectricity, piezoelectricity me te waku. He pānga whakaiti, ka taea te aukati i te pirau o te kai, ko te pānga tango haunga e ono ngā wā i te waro whakahohe, ka taea te tawhiti rawa atu i te hihi infrared me te whakatairanga i te whakatupuranga hou o ngā mihi. He āhua pumau tēnei pānga.

Rahi
0.5-1.5mm, 2-3mm, 3-4mm, 4-5mm, 5-6mm, 6-7mm, 7-8mm, 8-9mm, 9-10mm.

Tono
1. Whakaitihia te rōpū ngota wai, kia māmā ai te uru ki roto i te kiriuhi pūtau, kia nui ake ai te mahi a te pūtau, kia nui ake ai hoki te ārai mate o te tangata.
2. Whakakorehia te haunga rerekē me te toenga o te hauwai wai, whakakorea ngā matū kino me ngā carcinogens.
3. He ngoikore te kounga o te wai, ā, he kawakore, he mea e pai ai te taurite waikawa-pūtake me te taurite kai o te tinana tangata.
4. He nui te konupūmā, te konupora, te konutai, te pāhare pāporo me ētahi atu matū iti me ngā kohuke e hiahiatia ana e te tinana tangata.
5. He kawe hiko teitei, he iti te pūmanawa whakaiti-waikura (OPR), e whakatairanga ana i te nakunaku, e ārai ana i te koroheketanga, ā, e whai hua ana mō te roa o te ora.
6. Ahakoa te āhua o te rā, te pāmahana me te pēhanga, kāore e rerekē te whai huatanga me ngā āhuatanga o te hua. He pai mō te maimoatanga wai inu me te maimoatanga wai kaukau.
