2024 May -akda: John Day | [email protected]. Huling binago: 2024-01-30 13:13

Ang light polusyon ay isa sa maraming mga problema sa mundo. Para malutas ang problemang iyan, kailangan nating malaman kung magkano ang gabi sa kalangitan na nadumihan ng artipisyal na ilaw. Maraming mag-aaral na may mga guro sa mundo ang sumusubok na sukatin ang light polusyon sa mga mamahaling sensor. Napagpasyahan kong palitan ang aking portable luxmeter (para sa higit pang suriin ang nakaraang proyekto na maaaring turuan ng Portable Luxmeter) sa istasyon ng panahon na may TSL2591 sensor. Ang sensor na ito ay sapat na sensitibo para masukat ang polusyon sa gabi. Gayundin, nagdaragdag ako ng HTU21D para sa sukat ng temperatura at halumigmig.

Hakbang 1: Ano ang Polusyon sa Gabi at Paano Ito Sukatin

Ang polusyon sa gabi ay ilaw mula sa mga ilawan, kotse, bahay, malaking lcd panel sa lungsod at bawat ilaw na gawa ng tao. Ang ilaw na iyon ay tinatawag na artipisyal. Para sa mga nagmamasid, ang artipisyal na ilaw ay pangunahing problema upang makita ang mga bituin mula sa lungsod, at dapat silang lumabas sa labas ng lungsod. Para sa tao, mapanganib ang mataas na polusyon sa ilaw. At para din sa mga puno, damo at hayop.

Para sa pag-check ng light polusyon ng iyong lugar, makikita mo rito ang lightpollutionmap

Ito ay modelo lamang, at ang mga tunay na halaga ay maaaring magkakaiba. Iyon ang dahilan kung bakit nilikha ko ang luxmeter na iyon.

Para sa pagsukat ng light polusyon, sinusukat ko lamang ang lux at kinakalkula ang lakas / arsec2.

Maaari kong kalkulahin mula lux hanggang candela bawat metro ng suqare:

1 cd / m2 = 1 lux

Ang kalakhan bawat parisukat na arcsecond (mag / arcsec2) ay naglalarawan sa background ng kalangitan sa gabi (tinatawag itong ilaw sa ibabaw).

Higit pa sa wiki: Liwanag ng ibabaw

Para sa pagkalkula ng cd / m2 sa mag / arcsec2 ay pormula:

[halaga sa mag / arcsec2] = Log10 ([halaga sa cd / m2] / 108000) / - 0.4

Hakbang 2: BOM

Para sa proyektong ito kailangan mo:

1. WEMOS D1 Mini o anumang microcontroller

(Gumagamit ako ng mga wemos, dahil ito ay pinakamaliit, na may usb port, maaari mong subukan ang Arduino Nano)

WEMOS D1 MINI (Yanwen Economic Air Mail)

9. kaso, lumilikha ako mula sa kahoy + tape

red tape

Prusa 3D printer, sana ay gawin ko ang kaso mula sa plastic: D

Hakbang 3: Circuit

Ang circuit ay medyo simple:

Ikonekta ang lahat ng mga module ng i2c (TSL2591, OLED, HTU21D) sa SCL at SDA pin sa wemos (SDA -> D2, SCL -> D1).

Lakasin ang mga ito ng 3.3 V mula sa mga wemos.

Ikonekta ang plus terminal ng baterya sa 5V pin sa mga wemos at baterya + pin sa tp4056 singilin na module upang magdagdag ng terminal sa baterya.

Ikonekta ang lahat ng mga bakuran.

Hakbang 4: Sensor ng HTU21D

Bumibili ako ng bagong sensor ng temperatura, na sumusukat sa katumpakan na 0.3 ° C!

Mga bagay na dapat mong malaman tungkol sa sensor na ito (mula sa sparkfun):

• Gumagamit ng interface ng I2C
• Karaniwang kahalumigmigan ng kahalumigmigan ng ± 2%
• Karaniwang katumpakan ng temperatura ng ± 0.3 ° C
• Nagpapatakbo mula 0 hanggang 100% kahalumigmigan ngunit ang sensor na ito ay hindi inirerekomenda para sa malupit na mga kapaligiran kung saan maaari itong makipag-ugnay sa tubig (tulad ng ulan).
• 3.3V sensor - gumamit ng mga inline na antas ng converter ng lohika o 10k resistors upang malimitahan ang 5V signal
• Isang sensor lamang ng HTU21D ang maaaring manirahan sa I2C bus nang paisa-isa

Ang aking buod: ito ay mahusay na sensor, dahil sumusukat ito nang may katumpakan 0.3 ° C at pareho - temperatura at halumigmig. Ang mga kalamangan ay ang pagkagambala ng I2C at kahinaan ng 3.3V, ngunit hindi mahalaga sa aking kaso.

Hakbang 5: TSL2591

Ang sensor na ito ay mabuti para sa pagsukat ng polusyon sa kalangitan sa gabi dahil sa pagiging sensitibo nito (hanggang sa 188 micro lux!).

1. ay mga diode na may posibleng ir at buong sukat. Hindi ko ito ginagamit.

2. boltahe regulator mula 5V hanggang 3.3 V

Mga pagtutukoy ng Chip (mula sa adafruit):

• Tinatayang Tugon ng mata ng tao
• Labis na malawak na malawak na saklaw na 1 hanggang 600, 000, 000 na Mga Bilang
• Saklaw ng Lux: 188 uLux pagiging sensitibo, hanggang sa 88, 000 Mga sukat sa pag-input ng Lux.
• Saklaw ng temperatura: -30 hanggang 80 * C
• Saklaw ng boltahe: 3.3-5V papunta sa regulator ng board
• Interface: I2C
• Ang board / chip na ito ay gumagamit ng I2C 7-bit address na 0x29 (naayos)
• Mga Dimensyon: 19mm x 16mm x 1mm /.75 "x.63" x.04 "Timbang: 1.1g
• 2 diode para sa sukat pareho - IR at Buong spectrum

Buod:

Ang 188 uLux ay perferct, simple rin ang komunikasyon ng I2C. Marahil ay maaaring maayos ang problema sa I2C adress (0x29). Gayundin sa board regulator ay mabuti at posible na gumamit ng sensor sa panahon ng taglamig (frost).

Hakbang 6: Code

Kailangan mo ang mga libraryong ito (idaragdag ko ang mga ito sa isang zip file):

• Adafruit-GFX-Library-master
• adafruit_gfx_library_master
• Adafruit_HTU21DF_Library-master
• Adafruit_Sensor-master
• Adafruit_TSL2591_Library-master

Code: maaari mong gamitin ang minahan, o lumikha ng sarili. Huwag kalimutang itakda ang pinakamataas na oras ng pagsasama (600 MS) at makakuha sa max (GAIN_MAX) para sa panukalang langit sa gabi.

Kung susubukan mong gamitin ang aking code, mangyaring mag-download ng ino file. Kapag kinopya ko mula sa itinuro sa aking code, isang bagay na mali sa mga aklatan

Gumagamit ako ng loading image ng moon para lang sa kasiyahan. Maaari kang gumamit ng anuman, gamitin lamang ang pahinang ito para makakuha ng array:

Hakbang 7: Sa Loob

Lumilikha ako ng sariling kaso at gumagamit ako ng breadboard na may mga dupont cable na nakikita mo.

Gumagamit ako ng TP4056 para sa pagsingil ng baterya gamit ang usb cable (kailangan swtich dip jumper).

Para sa pag-on / off ay gumagamit ako ng dip jumper.

Para sa ilaw ng araw, ipinapakita ng TSL2591 ang 0 at ang mag / arcsec2 ay nan.

Para sa night sky dapat magpakita ang TSL2591 mula 0 hanggang 1000 000 microlux (ulux) at kaukulang mag / arcsec2

(cca. 14 hanggang 22 mag / arsec2).

Para sa fullMoon sinukat ko ang 50k ulux na 0.05 lux.
