Introduction After experiencing both a new boiler AND a washing machine leak in the same weekend I searched online for a network connected water leak detector. I wanted a device I could integrate into my home automaton system so I could both continually monitor the status of the detector (battery level etc.) and receive notifications. …

A few weeks ago, I purchased a Raspberry Pi. After reading Eben Upton’s Raspberry Pi User Guide, particularly the two chapters on which he focuses attention on the GPIO, I had an idea for my first project. The post covers the first iteration of a home temperature monitoring project I put together using a Raspberry …
This tutorial, based on the latest Raspberry Pi B+/model 2, will show you to interface a PIR motion sensor with the Raspberry Pi. And also guides you to use the GPIO pins on it. The GPIO pins on the raspberry pi are critical when it comes to making a hardware project. May it be a …

o detect a fart with the Raspberry Pi, we need to use a sensor that is responsive to one or more of the volatile sulphuric compounds which make up 1% of flatulence (i.e. the compounds which make farts smell). Essentially, we need to give the Raspberry Pi a nose. The sensor recommended for this project …

Ultrasonic distance sensors are designed to measure distance between the source and target using ultrasonic waves. We use ultrasonic waves because they are relatively accurate across short distances and don’t cause disturbances as they are inaudible to human ear. HC-SR04 is a commonly used module for non contact distance measurement for distances from 2cm to …

To measure the indoor or outdoor temperature with the Raspberry Pi, there are several possibilities. This article describes the version with the minimal amount of external components. This is based on the DS18S20 temperature sensor and the software emulation of the 1-wire protocol. The DS18S20 and related DS18B20 and DS1822 are integrated circuits in a …
