Adding More Temp Sensor

Since my previous post I have added a couple additional temperature sensors to my piHouse project.  One is an outdoor temperature sensor that I previously programmed but never installed outside, and the other is a new sensor in my bedroom.  This involved some hardware planning and effort installing because I had to run a cable through the house and outside, but once I tested the new cable run, it was relati ...

Raspberry Pi Thief Detector

What is a Raspberry Pi ? The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the inte ...

Test DS18B20 sensor

sudo modprobe w1-gpio sudo modprobe w1-therm cd /sys/bus/w1/devices ls cd 28-xxxx (change this to match what serial number pops up) cat w1_slave The interface is a little unreliable, but fortunately it tells us if there is a valid temperature to read. It’s like a file, so all we have to do is read The response will either have YES or NO at the end of the first line. If it is yes, then the temperature will b ...

Solar Driveway Light to MSP430 Wireless Sensor Node

The basic idea of this project is to convert a $3-4 solar light found at Lowes and Home Depot hardware store (here in the US) into a wireless remote sensor node.  The node will utilize an MSP430G2553 MCU and a nRF24L01+(w/ spirilis library) wireless module to send light intensity (photoresitor that came with solar driveway light), soil moisture (design from http://gardenbot.org), and soil temperature data ( ...

A simple analog proximity sensor with digital interface (for Raspberry Pi) [last update: Feb 7, 2014]

Raspberry Pi has a Broadcom BCM2835 chip, which controls 26 GPIO (general purpose input/output) pins. There are C library or RPi.GPIO python package available online that can be used to control the pins. The RPi.GPIO package is by default included in most Raspberry Pi system, such as Raspbian, a RPi version of Debian linux system. One drawback of RPi, compared to arduino, is that it doesn't have any analog ...

Motion Detection Alarm System

A basic USB camera can be used to detect motion in a room. In the following steps we will show you how you can use Reactive Blocks to program a ready to run Java application that sends SMS when motion is detected. With Reative Blocks you make Java SE applications so the alarm application can be deployed on any machine with Java SE and a camera attached or integrated. The application is easily deployed on th ...

Raspberry Pi Soil Moisture Sensor

Agriculture consumes between 80 - 90% of all freshwater in the United States. An easy way to conserve water in the agricultural sector is to install a soil moisture sensor. Soil moisture sensors measure the amount of water in the soil to maintain consistent and ideal soil conditions for plants. In some cases, installing a soil moisture sensor reduces residential irrigation by as much as 50%. The following i ...
