What connection do i need to make?

in using raspberry pi and the temperature sensor, following the above commands, instead of displaying it on the LCD, how do i get it to be displayed on the software installed on the android device.

Thanks

i have followed all the steps but in the it says w1_slave is not found
pi@raspberrypi:~ $ sudo modprobe w1-gpio
pi@raspberrypi:~ $ sudo modprobe w1-therm
pi@raspberrypi:~ $ cd /sys/bus/w1/devices
pi@raspberrypi:/sys/bus/w1/devices $ ls
00-800000000000 w1_bus_master1
pi@raspberrypi:/sys/bus/w1/devices $ cd 00-800000000000
pi@raspberrypi:/sys/bus/w1/devices/00-800000000000 $ cat w1_slave
cat: w1_slave: No such file or directory

can you please tell what can be the problem?

thank you

I have received message “modprobe: FATAL: Module w1–gpio not found” Please could you give me information what is wrong? I went step by step according to tutorial.
Thank you very much

Can this project be done without using it, i.e by fitting the Temperature Sensor into the breadboard itself?

I dont need an led screen do you have a tutorial for that?

Take a look at this tutorial on the DHT22: http://www.rototron.info/dht22-tutorial-for-raspberry-pi/

How can I do this with three sensors? Three DS18b20 and print it on the lcd?
