NTAU:

1 Hauv qhov haujlwm no kuv qhia yuav ua li cas txhawm rau tsim lub tshuab ntsuas qhov me me nrog cov ntaub ntawv tso tawm, cov ntaub ntawv thaub qab ntawm SD daim npav thiab IOT. Pom qhov muag neopixels ntiv nplhaib qhia pom huab cua zoo.

2 Huab cua zoo yog qhov kev txhawj xeeb tseem ceeb ntxiv niaj hnub no. muaj cov kab ke los ntsuas cov hmoov av tab sis lawv kim heev. Muaj tus nqi qis, ntsuas tau zoo hauv lub khw, raws li qhia los ntawm qee qhov kev tshawb fawb.

piv txwv:

www.atmos-meas-tech.net/11/4823/2018/amt-1…

3 Kuv thiaj li txiav txim siab tsim lub cuab yeej muaj peev xwm ntsuas tus lej ntawm cov chav kawm me me (0.5µm txog 10 µm), pom qhov muag nrog cov lus yooj yim ntawm qhov tshwm sim (neo pixel ring), ntxaws ntxaws ntxaws ntawm TFT screen thiab lub sij hawm-thwj thaub qab ntawm SD daim npav.

4 Tsis tas li ntawd kuv tau ntxiv qhov kev sib tham bluetooth kom muaj peev xwm sib txuas lus nrog Android daim ntawv thov thiab yog li tshaj tawm cov txiaj ntsig ntawm IOT server.

5 Tus nqi tag nrho ntawm tag nrho tsis tshaj 60 €
