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
