P916 Digital Intelligent Pyroelectric Infrared Pūoko 3pin pūoko matihiko me te 2s wā whakaroa

P916 Digital Intelligent Pyroelectric Infrared Pūoko 3pin pūoko matihiko me te 2s wā whakaroa

Ko te P916 he pūoko infrared pyroelectric e whakauru ana i te iahiko mana whakahaere atamai me tetahi huānga tairongo kitea tinana tangata i roto i te uhi whakamarumaru hiko. Ka honoa e te pūoko tairongo tinana tangata te tohu nekehanga tinana ki te maramara ara iahiko whakauru atamai ma roto i te ara iahiko urunga paheketanga tino teitei. Ka huri te ara iahiko whakauru atamai mamati i te tohu ki te tohu mamati ADC 15-bit ka nui ake te tohu PIR i te takirere mamati kua tohua. Ko te uara he putanga taumata REL kua whakaritea.

P916 Digital Intelligent Pyroelectric Infrared Sensor Digital Intelligent Pyroelectric Infrared Sensor Pyroelectric pūoko pōkākā pūoko PIR mamati 2s te wa whakaroa pūoko nekehanga tangata PIR pūoko te kaitirotiro tangata

Ko nga ahuatanga

Te tukatuka tohu mamati me te iti o te whakamahi hiko me te whakaoho tere.
Ko te whakaurunga pūoko impedance teitei me te kaha rerekee-rua.
Butterworth bandpass tātari o te ota tuarua ki te pūoko pōkākā mō te ārai pokanoa.
Putanga o Schmitt REL pūoko i runga i te tairongo, te wa, me te whakamarama.

Whakatupato

● Ko nga stains i runga i te Matapihi ka pa ki te mahi rapunga

● Rauemi Arotahi me te Aukati Paanga

He mea hanga te arotahi mai i te papanga ngawari e kiia nei ko te polyethylene. Ma te pehanga, ma te kaha ranei ki te arotahi ka paheke te ahua me te kino, ka hua he kino te mahi me te heke o te mahi. He mea nui kia tupato me te aukati i nga ahuatanga penei.

● Whakatupato Hiko Pateko

Ko te kore e tuku i te hiko pateko o ±200V teitei ake ranei ka raru. Na reira, he mea nui kia mahara i te wa e mahi ana me te aukati i te whakapiri tika ki te tauranga ma te whakamahi ringa kau.

● Aratohu Soldering

I te wa e whakapiri ana i te waea, me whakarite kia kaua e neke ake te wera o te rino i te 350 ° C me te whakaoti i te mahi whakapiri i roto i te 3 hēkona. Ko te whakapiri i roto i te pati konohi ka paheke pea te mahi, no reira he pai ke ki te karo i tenei tikanga.

● Whakatupato Horoi Pūoko

A ape i te horoi i te pukoro kia kore ai e kuhu te wai horoi ki roto i te arotahi, ka kino te mahi.

● Waea Tiara mo te Waea Waea

I te wa e whakamahi ana i nga waea waea, e taunaki ana kia whakamahia nga waea maru hei whakaiti i te pokanoa me te pupuri i nga mahi tino pai.
