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

Lub tsev kawm ntawv no yog siv los sau cov kev txhim kho ntawm cov txheej txheem dej xyuas dej tsis siv neeg. Cov kev ntsuas ntsuas yog qib dej thiab dej kub. Lub hom phiaj ntawm txoj haujlwm no yog txhawm rau txhim kho tus nqi qis thiab tus neeg logger ywj pheej uas txuas nrog lub hauv paus. Cov dej tau soj ntsuam nrog qib tshwj xeeb QR-qib. Lub koob yees duab hauv Pi tau thaij duab txhua 15 feeb. QR-cov lej hauv daim duab no tau txiav txim siab los ntawm software thiab yog qhia txog qib dej tiag. Dej kub ntsuas nrog tus ntsuas DS18B20.
