Kab lus no yog qhov ua piv txwv ntawm kev siv Ultrasonic Distance Sensor HC-SR04.

Lub ntsuas yuav raug siv los ntsuas ntsuas los tsim "1 Meter Keep Away Alarm Gadget" rau lub hom phiaj sib txawv.

Lub hlwb ntawm cov cuab yeej no yog qhov zoo ATTINY85 ontController powered by 3.7V Lipo roj teeb.

Lub cuab yeej txuas nrog lub roj teeb TP4056.

GREEN LED teeb yog ntsuas qhov deb ntawm ib yam khoom loj dua 120 cm.

RED LED ntsais muag yog tias ntsuas nrug ntawm ib yam khoom qis dua 100 cm nrog lub suab nrov (nrov nrov).

Ib lub YELLOW LED ntsais yog tias ntsuas nrug deb ntawm ib yam khoom nyob nruab nrab ntawm [100, 120] cm nrog lub suab nrov nrov tsawg dua.

Khoom siv

Ntau tsab xov xwm piav qhia ntxaws tias HC-SR04 ua haujlwm li cas.

Hauv qhov ua piv txwv, HC-SR04 Ultrasonic Distance Sensor yog

1 - Ultrasonic Transmitter - Qhov no xa cov suab paj nruag ultrasonic, nws ua haujlwm ntawm 40 KHz

2 - Tus Txais Txais Ultrasonic - Tus txais yuav mloog cov suab sib kis. Yog tias nws tau txais lawv nws tsim cov mem tes tso tawm uas nws qhov dav tuaj yeem siv los txiav txim siab qhov nrug ntawm cov mem tes mus.
