Where I work, there is a very important room which houses lots of computers. The ambient temperature of this room has to be very cool to optimize performance of these systems. I was asked to come up with a monitoring system which has the ability to send some form of alert to a few people […]
Hardware Since I was replacing the PC with a Pi, I have only listed the Pi-specific hardware here because the relay unit remains the same: Model B Pi Piface Digital interface card Dallas Semiconductor (Maxim) DS9490R 1-Wire USB adapter Dallas Semiconductor (Maxim) DS18S20 1-Wire thermometers The block diagram below shows the general arrangement of the

Introduction Every lab (home, office, school) needs temperature measurement capabilities. Measuring temperature for science experiments is hard – all sorts of materials, liquids, and chemicals may be involved or a large temperature range may need to be covered. The sensor used for this (a thermocouple) is not easy to interface, and the sensor amplifier is

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

Introduction Following on from using a Raspberry Pi to capture the electricity consumption of my home, I have over the last 2 years installed Solar Thermal Hot Water panels and very recently Solar PV. This meant that I had an opportunity to create something I had been looking to do for a while – an

Our hackerspace (Bloominglabs) recently received an ADS-WS1 weather station from a generous benefactor. Additionally, we were selected by Instructables for the Raspberry Pi 2 hackathon so we got some RPi2’s to hack on. For my project, I decided to use an RPi2 to put our weather station online. Our station can measure wind direction, wind

Build a personal weather station with Raspberry Pi that emails you the temperature, humidity, and rainfall. *In a couple of weeks I will be adding a barometric pressure sensor to calculate chance of rain. Step 1: Supplies You will need: Raspberry Pi b and power supply Ethernet cable Breadboard wires Breadboard Humidity & Temperature module

The Problem: I recently remodeled my home office and I now have a dedicated closet for my electronics (Server, NAS, AV Receiver, etc.) During the build I planned for heat remediation by installing an exhaust fan that dumps air from the closet into my adjoining office. However, the temperature in the closet hovers around 90°F

Beer brewing is a fun hobby, whether you wanna just brew something easy from a kit, or take the time to fine-tune your preferred style. With every batch, there are always two things that weigh heavy on a brewer’s mind: risk of contamination or, depending on where you live, extreme temperatures. I live in an
