ʻO ka mea hoʻoheheʻe kiʻekiʻe-pololei 3cm makapō mea ʻimi ultrasonic range (DYP-A20)

Loaʻa nā hiʻohiʻona o ka module A20 me ka hoʻonā millimeter, 3cm a 300cm ka laulā, ke kūkulu ʻana a me nā ʻano hoʻopuka he nui: PWM pulse width output, UART controlled output, UART automatic output, switching output, RS485 output.

Eia hou, ke kānana ʻo Firmware no ka hoʻomanawanui leo maikaʻi a me ka hōʻole ʻana

mm pae hoʻonā
ʻO ka hana uku pānaʻi ma luna o ka papa, hoʻoponopono maʻalahi o ka hoʻokaʻawale ʻana o ka mahana, paʻa mai -15 ° C a +60 ° C
40kHz ultrasonic sensor ana i ka mamao i ka mea
ʻO RoHS kūpono
Nui nā mea hoʻopuka puka koho: PWM pulse ākea, UART hoʻomalu, UART aunoa, Hoʻololi, RS485
ʻO ka pahu make 3cm
ʻO 300cm ka lōʻihi
He 3.3-5.0V, 5.0-24.0V (RS485) ka voluma hana.
Ke hana nei ≤8mA, ≤15mA (RS485)
ʻO ka hoʻolālā hoʻohana haʻahaʻa haʻahaʻa, kū i kēia manawa ≤5uA
Ke ana pololei o nā mea mokulele: ±(1+S*0.3%)cm, S hōʻike i ka mamao ana
Module liʻiliʻi a māmā
Hoʻolālā ʻia no ka hoʻohui maʻalahi i kāu papahana a huahana paha
Ka wela hana -15°C a +60°C
IP67 pale wai

Manaʻo no ka pale ʻana i ka pale a me ka hoʻokele ʻakomi
Manaʻo no ka pili kokoke ʻana i nā mea a me nā noi ʻike maka
Manaʻo no ka ʻōnaehana hoʻokele kaʻa
Manaʻo no ka ʻike kiʻekiʻe o ka pae wai wai
