Testing PCsensor's “TEMPerHUM” Phase 2: Testing PCsensor's “TEMPerHUM” in Windows XP environment As we discussed in Phase 1, it was needed to have .NET Framework installed on a Microsoft Windows based computer in order to install PCsensor’s software TEMPerHUM. However, some users might not want to install that software, but instead to use the TEMPerHUM hardware’s ability to send monitored data to an empty file that was previously opened in the Windows’ foreground. (Why the...

Testing PCsensor's “TEMPerHUM” Phase 1: Testing PCsensor's “TEMPerHUM” in Windows XP environment At first I wanted to test this sensor device in Microsoft Windows environments for which the producer dispatched an end-user software, named also TEMPerHUM, in its version 25.6 that at the time (mid-2017) was sent on a mini-CD alongside with the sensor in the box. For that purpose I used an old test desktop computer that was configured for dual-boot with Linux and...

If you want to detect an "output" with your Raspberry Pi, like a button being pressed or a motion sensor detecting movement, we can configure our Raspberry Pi's GPIO pin as an "input". That input pin can be in three states (known as Tri-State logic); "high", when 3.3V is applied, "low", when the pin is connected to 0V, and "floating" when the state is undefined. Floating voltages are troublesome in electronics as the input can...

What you need to get started with the Raspberry Pi The Raspberry Pi, just like any other computer you may have used, will need a few accessories for it to be fully functional and programmable. It is essentially a mini-computer, just on a single circuit board, making it light, compact and most importantly, affordably cheap! Below is some information about what you will need to get started: What you need

Which OS is best? There are so many OS (Operating System) options out there for the Raspberry Pi, it makes choosing the right one for you a bit of a mine field!  First of all, what exactly is an OS and why do you need one?  Essentially, an OS is the software that supports a computer’s basic functions. For example, a computer needs an OS to execute scheduling tasks, control peripherals and execute...

Blinking an LED in python has become really easy due to the new GPIO Zero library. There's a few different ways. Lets begin by just turning the amber LED on. Open up your favourite python editor and type in the following to turn it on. from gpiozero import LED amber = LED(23) amber.on() And then try "amber.off()" to turn it off. We can make the LED now blink by adding the following code at...

Following on from the previous tutorial of blinking an LED using GPIO Zero we're going to expand into creating a traffic light program. However instead of using the separate modules for the LED And buzzer there is a neater way that we can do it using the TrafficHAT Add-on function. Begin by adding the following code to setup the TrafficHAT replacing Ryan Walmsley with your name. #TrafficHAT Program #TrafficLight By Ryan Walmsley from gpiozero...
