Raspberry Pi temperature sensor script

Simple python script for connecting a DS18B20 temperature sensor to a Raspberry Pi. It can print either the temperature (configurable for Celcius or Farenheit) or the temperature and a timestamp.

This is still under construction. Tread lightly.

Getting Started

Prerequisites

You will need:

• a Rasperry Pi with SSH access
• a DS18B20 temperature sensor

Set up temperature sensor

I followed this guide to set up the temperature sensor, if you have not already. It can be found here:

Adafruit Guide

Installing

1. Make sure your Pi is updated, then install modprobe.

$ apt-get update 

$ apt-get install modprobe

2. Connect your DS18B20 temperature sensor to the Raspberry Pi

3. Find the serial of the temperature sensor

cd /sys/bus/w1/devices
ls

This will list all of the devices in the GPIO board.

Change to the one that ends in 28-xxx

then type cat 28-xxx to make sure it's collecting data.

Deployment Notes

• Wired internet is usually more stable than a wifi dongle

• If you want to add this as a cron job, you can use thermcron.sh (or see below) to run it as often as you want.

python /root/thermo.py >> /root/temp_log.csv

Built With

• Sublime Text
