Iyo solar sensor mwenje inoshandisa solar panel kuchaja bhatiri rinochajwa. Kana zuva richipenya zvakajeka, solar panel inogadzira ikozvino uye voltage yekuchaja bhatiri. Husiku, bhatiri rinoburitsa simba kumutoro rinodzorwa nehungwaru infrared uye optical switch.
Uyu musanganiswa weakawanda probes LED induction mwenje, akati wandei induction mwenje inogona kuve yakajairika, inochinjika kune mumwe nemumwe.
