MINI SMD Four Element Anti Jamming Digital Pyroelectric Infrared Sensor

Nalika sinyal infra merah pyroelektrik sing ditampa dening MINI SMD Four Element Anti Jamming Digital Pyroelectric Infrared Sensor ngluwihi ambang pemicu ing njero probe, pulsa ngetang bakal digawe internal. Nalika probe nampa sinyal kaya maneh, bakal dianggep wis entuk denyut nadi kaping pindho. Sawise nampa 2 pulsa sajrone 4 detik, probe kasebut bakal ngasilake sinyal alarm lan pin REL bakal duwe pemicu level dhuwur.

Mode pemicu output

Nalika sinyal infra merah pyroelektrik sing ditampa probe ngluwihi ambang pemicu ing njero probe, pulsa ngetang bakal digawe internal. Nalika probe nampa sinyal kaya maneh, bakal dianggep wis entuk denyut nadi kaping pindho. Sawise nampa 2 pulsa sajrone 4 detik, probe kasebut bakal ngasilake sinyal alarm lan pin REL bakal duwe pemicu level dhuwur.
Kajaba iku, anggere amplitudo sinyal sing ditampa ngluwihi luwih saka 5 kali ambang pemicu, mung siji pulsa sing dibutuhake kanggo micu output REL. Gambar ing ngisor iki minangka conto diagram logika pemicu. Ing pirang-pirang pemicu, wektu pangopènan output REL diwiwiti saka pulsa sing valid pungkasan.



Setelan wektu pin ONTIME
Nalika probe kasebut ndeteksi sinyal gerakan awak manungsa, bakal output level dhuwur ing pin REL. Durasi level iki ditemtokake dening level sing ditrapake menyang pin ONTIME (deleng tabel ing ngisor iki). Yen piranti level dhuwur REL duwe pirang-pirang sinyal pemicu sing digawe, angger sinyal pemicu anyar dideteksi, wektu REL bakal disetel maneh, banjur wektu bakal diwiwiti maneh.

1. Arus kerjane gegandhengan karo resistensi sing dipilih. Rintangan luwih gedhe, arus listrik saya cilik. Rata-rata arus sing dikonsumsi R sajrone wektu tundha efektif efektif yaiku: IR â ‰ ˆ 0.75VDD / R. Sajrone wektu tundha sing ora efektif, R ora nggunakake arus. Yen sampeyan duwe syarat konsumsi daya sing dhuwur lan asring ing wektu tundha efektif, disaranake nggunakake mode wektu REL digital.


2. If the digital REL timing mode is adopted, the ONTIME pin is connected to a fixed potential whose maximum value is less than VDD / 2 (in actual use, the resistor divider can be used to adjust the REL timing). The ONTIME input voltage sets the REL output holding time through the only trigger. Refer to the table below for the output delay timing (Time Td) and voltage settings. Cathetan: When using the digital REL timing method, the ONTIME pin voltage must not be higher than VDD / 2, and the timing time can only be selected from one of the 16 times in the table below. If the time in the table below is not suitable, it is recommended to use the analog REL timing method.

The voltage input by SENS sets the sensitivity threshold, which is used to detect the strength of the PIR signal input by PIRIN and NPIRIN. When grounded, it is the minimum voltage threshold, and the sensitivity is the highest at this time. Any voltage exceeding VDD / 2 will select the maximum threshold. This threshold is the lowest sensitive setting for PIR signal detection, that is, the sensing distance may be the smallest. It should be pointed out that the sensing distance of the infrared sensor is not linearly related to the SENS input voltage. Its distance is related to the signal-to-noise ratio of the sensor itself, the imaging object distance of the Fresnel lens, the background temperature of the moving human body, the ambient temperature, the ambient humidity, and electromagnetic interference. And other factors form a complex and multiple relationship, that is, the output result cannot be judged by a single index, and the debugging result shall prevail in actual use. The lower the voltage of the SENS pin, the higher the sensitivity, and the longer the sensing distance. There are a total of 32 sensing distances to choose from, and the closest sensing distance can reach centimeter level. In actual use, the resistance divider can be used to adjust the sensitivity.


Setelan pin OEN

OEN minangka pin aktif kanggo output REL. Nalika OEN input voltase kurang, output REL mesthi kurang; nalika OEN input voltase dhuwur, nalika pin PININ / NPIRIN ngrasakake sinyal pemicu awak manungsa lumra liwat sensor, REL ngasilake level dhuwur nganti ora ana sinyal pemicu awak manungsa, lan pass REL Sawise wektune wektu, REL output kurang tingkat Sawise wektu tameng udakara 2 detik, sinyal awak manungsa bisa dirasakake maneh. PIN OEN bisa disambungake menyang fotoresistor utawa fotodiode kanggo nyadari fungsi ora bisa digunakake nalika awan lan kerja ing wayah wengi.

Solder ulang
Pandhuan solder sensor
Nalika solder sol, mangga tindakake kurva suhu sing ditampilake ing gambar ing ngisor iki. Apa wae sing ngluwihi suhu refleksi sing ditampilake ing gambar ing ngisor iki, kudu takon karo insinyur sales sadurunge.


Kemasan


Cathetan: The standard package is 1000 pieces, and the package quantity and size vary slightly according to different models.

Cathetan for welding
Aja ngluwihi suhu maksimum kurva suhu sing ditampilake ing gambar ing ndhuwur, yen bisa nyebabake kerusakan kinerja sensor.
Aja ngulang soldering refow lan pemanasan lan pembongkaran bola-bali, sing bakal mengaruhi urip lan kinerja sensor kanthi serius lan ora dijamin karo garansi produk.
Aja nggunakake bahan kimia korosif kanggo ngresiki saringan optik (bisa digunakake etanol absolut), sing bisa nyebabake sensor ora berfungsi utawa gagal. Aja nggunakake langsung sawise sensor dipasang, disaranake nggunakake sawise 1H.
Be careful not to touch the terminals with metal pieces or hands. Cathetan for welding:

Rentang lingkungan operasi (asor)
> Temperature: Working temperature: -30℃~+70℃ (no fog or icing, temperature change may cause sensitivity and distance change) Suhu panyimpenan: -40℃~ +80℃
Kelembapan: Kelembapan sing digunakake: â ‰ ¤ 85% RH (ora kudu fogged utawa beku)
Kelembapan panyimpenan: â ‰ ¤ 60% RH
Babagan suhu lingkungan panggunaan lan ruang lingkup adaptasi, nuduhake suhu lan asor sing bisa nggawe sensor bisa terus, dudu jaminan kerja terus-terusan kanggo daya tahan lan resistensi lingkungan. Yen digunakake ing suhu dhuwur lan lingkungan asor sing dhuwur, sensor bakal nyepetake penuaan.

Wawasan liyane
Salah operasi bisa uga amarga gangguan elektroterma kayata listrik statis, kilat, telpon seluler, radio, lan cahya kanthi intensitas dhuwur.
Produk terminal pelanggan kudu dipasang kanthi kuwat kanggo ngindhari kerusakan sing nyebabake angin lan geter.
Iki bakal rusak sawise geter utawa pengaruh sing kuat lan nyebabake kerusakan. Nyingkiri getaran utawa pengaruh sing kuat banget.
Produk iki dudu produk anti banyu lan anti debu. Sampeyan kudu anti banyu, anti debu, anti kondensasi lan anti-es nalika nggunakake.
Yen gas korosif volatilisasi ing lingkungan kerja, bakal nyebabake kerusakan.
