Qhov no yog thawj lub tswv yim uas tau muaj rau micro: qhov tob tob ntsuas, qhov kawg yuav tsum tau tsim.

Ntawm no kuv tau siv lub ntsuas BMP280 rau 5m ntawm 4-xaim cable thiab tso poj niam jumper ntawm lwm qhov kawg. Txhawm rau tiv thaiv lub ntsuas hluav taws xob los ntawm dej, txoj hlua tau khiav los ntawm kev siv cawv cork. Qhov kawg ntawm lub cork raug kaw nrog cov kua nplaum kub. Ua ntej kuv tau txiav ob lub thais rau hauv lub cork, ob qho tib si mus ncig nws. Tom qab ntawd kuv ntim lub ntsuas mus rau hauv lub pob daim txhuam cev, tso ib lub zais pa nyob ib puag ncig nws thiab kho qhov kawg ntawm lub zais pa ntawm lub cork (qis qis dua). tom qab ntawd kuv tau tso 3 40 g cov hmoov txhuas hnyav rau hauv lub zais pa thib ob, qhwv nws ib puag ncig thawj qhov, qhov hnyav tau muab tso rau sab nraud, thiab kho qhov kawg ntawm lub zais pa ntawm qhov thib ob. Cov cua tau raug tshem tawm ntawm lub zais pa thib ob, tom qab ntawd txhua yam raug kho nrog kab xev. Saib cov duab, cov ncauj lus kom ntxaws yuav ua raws.

Cov dhia tau txuas nrog lub micro: me ntsis ntawm qhov txuas txuas, lub cuab yeej hloov pauv thiab siv qhov ntsuas siab tau teeb tsa. Tom qab ntawd lub taub hau sensor tau tso tawm qeeb rau hauv qab ntawm lub pas dej (10 m dhia ntauwd, txog 4.5 m tob).

Cov txiaj ntsig:

Ua rau kuv xav tsis thoob, nws ua haujlwm txawm tias nrog cov kab ntev no. Ntawm qhov tod tes, tab sis tsis xav tsis thoob, qhov ntsuas yuam kev zoo li ua rau loj dua ntawm kev sib zog siab, thiab kwv yees qhov tob ntawm 4 m tau tshaj tawm txog li 3 m.

Tej zaum daim ntawv thov:

Nrog qee qhov kev kho yuam kev, lub cuab yeej tuaj yeem siv los ntsuas qhov tob txog 4 m.

Ua ke nrog Arduino lossis Raspberry Pi, qhov no tuaj yeem siv los ntsuas thiab tswj cov chaw ntim ntawm lub pas dej lossis lub taub dej, e, g. kom tshaj tawm ceeb toom yog tias cov qib dej mus siab dua lossis qis dua qee qhov pib
