Kev qhia yooj yim ntawm yuav teeb tsa DS18b20 qhov ntsuas kub nrog raspberry pi.
Kauj Ruam 1: Qhov Chaw
Yam Yuav Tsum Tau:
RPI 3 -
4 Amp Power Adapter -
16GB micro SD -
120 pcs jumper cable:
ds18b20 sensor -
Kauj ruam 2: Teeb
1. Kho config.txt
sudo nano /boot /config.txt
ntxiv "dtoverlay = w1-gpio" rau hauv qab ntawm cov ntawv
sudo rov pib dua
2. Ntaus cov lus txib hauv qab no
sudo modprobe w1-gpiosudo modprobe w1-therm
cd/sys/npav/w1/khoom siv/
ls ua
3. hloov cov npe rau sensor piv txwv
cd 28-00000xxxxxxx *tus lej xov tooj yog qhov tshwj xeeb
4. xyuas seb lub sensor puas ua haujlwm
miv w1_slave
koj yuav tsum pom cov zis zoo ib yam li qhov no
hauv paus@raspberrypi:/sys/bus/w1_slave/28-00000495db35# miv w1_slavea3 01 4b 46 7f ff 0d 10 ce: crc = ce YES
a3 01 4b 46 7f ff 0d 10 ce t = 26187
