- Kub Ntau Yam: -55 ° C txog +125 ° C.

- Qhov tseeb: ± 0.5 ° C.

- Cim 64-ntsis chaw nyob ua rau muaj kev sib txuam.

Kauj ruam 4: LCD

LCD tswj nrog 16 × 2 cim cim qauv nrog xiav

backlight thiab cov cim dawb. 2 kab, 16 tus cim ib kab. Siab sib txawv thiab pom lub kaum ntse ntse loj. Qhov sib piv tau kho tau los ntawm kev kho qhov hloov pauv tau (potentiometer / trimmer).

LCD 16 × 2 qhov tshwj xeeb xiav:

- Ua haujlwm: 5V

- Kho qhov sib txawv.

- Qhov ntev: 80mm x 35mm x 11mm.

- Pom pom pom: 64.5mm x 16mm.

Kauj Ruam 5: MCP3008

Ib qho piv txwv-rau-digital hloov pauv lossis AD-hloov pauv (ADC) hloov pauv cov lus sib piv, piv txwv li hais lus teeb liab, rau hauv cov cim digital. MCP3008 muaj 8 cov tswv yim sib piv thiab tuaj yeem nyeem nrog SPI interface ntawm Arduino, Raspberry Pi, ESP8266 MCP hloov pauv qhov hluav taws xob sib piv rau tus lej ntawm 0 thiab 1023 (10 ntsis).

Thaum siv MCP3008 koj yuav tsum tau pab kom SPI, koj tuaj yeem ua qhov no los ntawm (cov duab ntxiv nrog cov kauj ruam):

1. Ntaus hauv lub console: sudo raspi-config
2. Qhov no yuav tshaj tawm cov txiaj ntsig raspi-teeb tsa. Xaiv "Interfacing Options"
3. Nyeem qhov kev xaiv "SPI" thiab qhib.
4. Xaiv thiab qhib.
5. Highlight thiab qhib.
6. Thaum hais kom rov pib dua qhov tseem ceeb thiab qhib.
7. Raspberry Pi yuav rov pib dua thiab lub interface yuav raug qhib.
