    buleh..mmg sensor jenis ni yg paling femes utk water level detector..cuma plat tu jgn rapat sgt..jauhkan sikit asalkan tompok air tak buleh shortkan plat tu..plat tu even jarak 1 inci pon masih buleh berfungsi kalu kena air..aku dah try..
    air bukanlah konduktur elektrik yg baik..sebab dia xde free charged ions..utk high voltage/current..maybe xde masalah..utk low voltage/current..it quite impossible..sebab aku penah try bt sambungan..mmg xde connection..aku try gune multimeter (mode connection test)..pun xde connection..unless kena ada circuit tertentu utk amplify the current/voltage n compare dgn satu voltage reference..

    aku ckp berdasarkan ape yg aku blajar masa diploma (electrical engineering) dulu la..aku xdela terer mane..tp based on ape yg aku blaja n experience aku la..kalo salah..tolong btolkan..

    assalamualaikum...

    hmm buleh jadi jugak..sebab dulu aku try kat circuit yg guna 12v dc..kalu ikut projek ko ni (2 x button cell , so -+ 3v dc?) musti ada beza tahap sensitif dia..lagipon nanti dah tentu nak guna kat air kopi, teh etc..komposisi air dah lain2..

    thanks..aku pon blaja sesuatu.. Smile dulu pon aku buat sekadar hobi je..

    btw ko nak guna bateri jenis LR44 kan? yg laser pointer guna tu..

    aku pun penah bt projek tu..mase form 3..projek KH..jgn katakan air..tangan ni pn bleh conduct..gune verabod gak..mmg kena ada circuit utk itu..n quite imposibble to use it in this device..(sbb melibatkan komponen yg besar) unless bleh bt dlm bentuk cip/ic..and of couse kos dia tinggi..

    yup..gune bateri jenis LR44..
