2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:27

Lub teeb qias neeg yog ib qho ntawm ntau yam teeb meem hauv ntiaj teb. Txhawm rau daws qhov teeb meem ntawd, peb yuav tsum paub ntau npaum li cas hmo ntuj ntuj tsis zoo nrog lub teeb ci. Coob tus tub ntxhais kawm nrog cov kws qhia ntawv hauv ntiaj teb sim ntsuas lub teeb qias neeg nrog lub ntsuas pa kim. Kuv txiav txim siab hloov kuv lub luxmeter portable (kom paub ntau ntxiv yav dhau los cov lus qhia ua haujlwm Portable Luxmeter) rau huab cua chaw nres tsheb nrog TSL2591 sensor. Qhov ntsuas no nkag siab txaus rau ntsuas kev ua paug hmo ntuj. Tsis tas li, kuv ntxiv HTU21D rau ntsuas kub thiab av noo.

Kauj Ruam 1: Dab Tsi Pollution Hmo Ntuj thiab Nws Ntsuas Li Cas

Hmo ntuj qias neeg yog teeb los ntawm teeb, tsheb, tsev, loj lcd vaj huam sib luag hauv nroog thiab txhua lub teeb tsim los ntawm tib neeg. Lub teeb ntawd hu ua khoom neeg. Rau cov neeg soj ntsuam, lub teeb pom kev yog qhov teeb meem tseem ceeb kom pom cov hnub qub los ntawm nroog, thiab lawv yuav tsum tawm mus sab nrauv lub nroog. Rau tib neeg, lub teeb qias neeg qias neeg yog teeb meem. Thiab kuj rau ntoo, nyom thiab tsiaj txhu.

Txhawm rau txheeb xyuas lub teeb qias neeg ntawm koj qhov chaw, koj tuaj yeem pom ntawm no lightpollutionmap

Nws tsuas yog tus qauv, thiab qhov txiaj ntsig tiag tiag tuaj yeem sib txawv. Tias yog vim li cas kuv tsim qhov luxmeter.

Txog kev ntsuas lub teeb qias neeg, Kuv ntsuas tsuas yog lux thiab suav qhov ntau/ arsec2.

Kuv tuaj yeem suav los ntawm lux rau candela ib suqare meters:

1 cd/m2 = 1 lux

Qhov loj ib square arcsecond (mag/arcsec2) piav qhia yav hmo ntuj ntuj tom qab (nws hu qhov ci ntsa iab).

Ntau ntawm wiki: Qhov ci ntsa iab

Txog xam cd/m2 rau mag/arcsec2 yog cov mis:

[tus nqi hauv mag/arcsec2] = Log10 ([tus nqi hauv cd/m2]/108000)/-0.4

Prusa 3D tshuab luam ntawv, Kuv vam tias kuv yuav ua cov ntaub ntawv los ntawm yas: D

Kauj ruam 3: Circuit Court

Circuit Court yog yooj yim zoo nkauj:

Txuas txhua i2c cov qauv (TSL2591, OLED, HTU21D) rau SCL thiab SDA tus pin ntawm wemos (SDA -> D2, SCL -> D1).

Hwj chim lawv nrog 3.3 V los ntawm wemos.

Txuas txuas ntxiv lub roj teeb rau 5V tus pin ntawm wemos thiab roj teeb + tus pin ntawm tp4056 them tus nqi ntxiv rau lub davhlau ya nyob twg ntawm roj teeb.

Txuas txhua thaj chaw ua ke.

Kauj Ruam 4: HTU21D Sensor

Kuv yuav cov ntsuas kub tshiab, uas ntsuas nrog qhov tseeb 0.3 ° C!

Yam uas koj yuav tsum paub txog lub ntsuas cua no (los ntawm sparkfun):

• Siv I2C interface
• Raug cov av raug ntawm ± 2%
• Raug ntsuas qhov tseeb ntawm ± 0.3 ° C.
• Ua haujlwm los ntawm 0 txog 100% cov av noo tab sis lub ntsuas cua no tsis pom zoo rau ib puag ncig hnyav uas nws tuaj yeem cuam tshuam nrog dej (xws li nag).
• 3.3V lub ntsuas hluav taws xob - siv inline logic qib hloov pauv lossis 10k resistors los txwv 5V cov cim
• Tsuas yog ib qho HTU21D sensor tuaj yeem nyob ntawm I2C tsheb npav ib zaug

Kuv cov ntsiab lus: nws yog qhov ntsuas zoo, vim nws ntsuas nrog qhov tseeb 0.3 ° C thiab ob qho tib si - kub thiab av noo. Pros yog I2C cuam tshuam thiab cuam tshuam 3.3V, tab sis nws tsis muaj teeb meem hauv kuv cov ntaub ntawv.

Kauj ruam 5: TSL2591

Qhov ntsuas no zoo rau ntsuas huab cua ntuj hmo ntuj vim nws nkag siab (rau 188 micro lux!)

1. yog diodes nrog tau ir thiab ntsuas tag nrho. Kuv tsis siv nws.

2. qhov ntsuas hluav taws xob los ntawm 5V txog 3.3 V

Chip specifications (los ntawm adafruit):

• 2 diodes rau ntsuas ob qho tib si - IR thiab puv spectrum

Ntsiab lus:

188 uLux yog qhov ua tau zoo, tseem I2C kev sib txuas lus yog qhov yooj yim. Tej zaum qhov teeb meem tuaj yeem kho I2C chaw nyob (0x29). Tsis tas li ntawm cov tswj hwm lub rooj tsavxwm yog qhov zoo thiab tuaj yeem siv lub ntsuas cua thaum lub caij ntuj no (te).

Kauj ruam 6: Code

Koj xav tau cov tsev qiv ntawv no (Kuv ntxiv lawv rau ib daim ntawv zip):

Kauj Ruam 7: Sab hauv

Kuv tsim tus kheej cov ntaub ntawv thiab kuv siv breadboard nrog dupont cables raws li koj tuaj yeem pom.

Kuv siv TP4056 rau them roj teeb nrog usb cable (xav tau swtich dip jumper).

Rau kev qhib/tua Kuv siv lub jumper poob.

Txog rau nruab hnub, TSL2591 qhia 0 thiab mag/arcsec2 yog nan.

Txog rau ntuj hmo ntuj yuav tsum TSL2591 qhia los ntawm 0 txog 1000 000 microlux (ulux) thiab sib xws mag/arcsec2

(cca. 14 txog 22 mag/arsec2).

Rau fullMoon Kuv ntsuas 50k ulux uas yog 0.05 lux.
