Kuv tus poj niam purcahsed no LED illumintaed kos npe thiab dai nws hauv peb txoj kev me me.

Nws tau zoo heev ntawm kev hloov nws, tab sis tsis nco qab heev hloov nws tawm! Qhov tshwm sim pom tseeb yog qhov tseeb peb tau hloov lub roj teeb ntau dhau!

Kuv txiav txim siab qhov kev daws teeb meem zoo tshaj plaws kom nws hloov pauv los ntawm lub sensor, tab sis kuv qhov kev txhawj xeeb tseem ceeb yog ntws ntawm cov roj teeb uas tshwm sim los ntawm lub ntsuas.

Tom qab ntawd kuv tau hla 'lub pov haum me me' PIR MH-SR602. Nws tsuas yog kos 20 micro amps, (yog micro amps) thaum hnov thiab nws muaj qhov kho tau 'ntawm' lub sijhawm ib yam nkaus!

Teeb meem daws!

100 uF capacitor (qhov tseem ceeb rau kev ruaj ntseg tiv thaiv tsis raug!)

100 K lub sijhawm tiv thaiv (qhov no tuaj yeem muaj txiaj ntsig ntawm 0 ohms & 316 M)

4.7K tiv thaiv

Muaj qee cov ntaub ntawv zoo ntawm tus xaib Aliexpress …

www.aliexpress.com/item/32948972482.html?s…

Daim duab ntawm kev tshaj tawm ntawm lub sijhawm tiv thaiv tau zoo dua li kuv daim duab!

Kuv tsis tau thab nrog cov rhiab rhiab resistor, Kuv tau tshem nws ua yuam kev, thiab kuv tsis thab nrog tus yees duab resistor. Kuv nrhiav tsis tau cov ntaub ntawv ntau ntxiv txog 2 lub luag haujlwm no tab sis kuv tsis xav tau!

Kuv tau hloov lub sijhawm tiv thaiv.

**** NCO TSEG **** Cov lus ntawm lub vev xaib aliexpress rau lub sijhawm tiv thaiv sib txawv rau qhov kuv tau siv! Kuv tsis paub tseeb tias vim li cas nws txawv, tab sis 100K resistor kuv siv tau muab rau kuv li 1 feeb 'ntawm' sijhawm !! (Google MH-SR602 thiab saib 'cov duab'!)

Lub neej ntawd 'ntawm' lub sijhawm yog 2.5 vib nas this.

100uF capacitor yog qhov tseem ceeb, zoo li tsis muaj nws, txhua yam kev ua tsis raug yuav tshwm sim!

Lub voj voog nws tus kheej nws zoo nkauj ncaj nraim rau pem hauv ntej.

Thaum MH-SR602 tau ua rau tus pin tso tawm mus siab rau lub sijhawm nyob ntawm lub sijhawm tiv thaiv thiab tig lub transistor rau, uas ua rau tso cai tam sim no ntws los ntawm LEDs.

Kuv tshem lub roj teeb tso rau hauv thiab muab lub voj voog nruab nrab ntawm cov roj teeb tsis zoo thiab lub roj teeb txuas. Kuv tau laum cov ntaub ntawv hauv qab thiab ntxig rau lub rooj tsav xwm me me.

Ua haujlwm tiav:-)
