Testing PCsensor's “TEMPerHUM” Phase 4: Testing PCsensor's “TEMPerHUM” in Linux environment In Phase 3 we talked about using TEMPerHUM temperature & humidity sensor in Linux GUI (graphical user interface)(graphical user interface). Now for those of you who prefer Linux CLI (command line interface), it would be needed to produce (or as it is said in Linux terminology, to make) an appropriate executable file by yourself because...

Testing PCsensor's “TEMPerHUM” Phase 3: Testing PCsensor's “TEMPerHUM” in Linux environment As we discussed in Phase 1 & 2, it was possible to use TEMPerHUM on a Microsoft Windows -based computer without any software, thankfully to the hardware’s ability to send monitored data to an empty file that was previously opened in the Windows’ OS foreground. To activate monitoring the temperature and humidity, it was enough to press the “TXT” button on the sensor device....

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...

If you find your WiFi mouse acting very slow, or even "rubber banding", theres a simple fix! The Raspberry Pi's USB poll rate for mice has been set slightly on the slow side, which has been causing issues with WiFi mice. By increasing the poll rate you can speed up and smooth out the laggy mouse movement. However it does come at a slight cost to CPU performance. To change the poll rate simply edit...

Use with the Raspberry Pi 3 and Zero W To get serial working over GPIOs 14 & 15 you have two options. Disable Bluetooth completely or move Bluetooth to the mini-UART. Disable Bluetooth If you don’t need to use Bluetooth the easiest option is to simply disable it. To do this edit the boot config file: sudo nano /boot/config.txt And add the following line: dtoverlay=pi3-disable-bt Then run the following command: sudo systemctl...
