  • Researchers develop a simple logger for greenhouse gas flows

    Researchers at Linköping University in Sweden have developed an Arduino-based logger to measure levels of methane and carbon dioxide in greenhouse environments. The device also implements a DHT22 temperature and humidity sensor, data from which can be correlated with gas readings. Figures are stored on an SD card using an Adafruit data logging shield.

    Importantly, the team’s study outlines a procedure for calibrating the methane sensor module at atmospheric concentrations, much lower than its normal use. The entire unit can be made for around €200, or about $235 USD. While an inexpensive method for monitoring CO2 has been available for some time, this fills in the need for a low-cost methane sensor that could be used for distributed measurements.

  • 5 Great IoT starter kits

    The Internet of Things sounded stupid at first, but as you get to know more about it, the more fascinating it is to figure out how it can be used in your toaster. The idea is that you create a small device that collects a small amount of data that it sends to a service that can draw conclusions from it. You can use the same technology for devices at home. Most kits contain a single board computer with sensors and a manual to help you get started. Distributors use a range of devices in these packages; the Raspberry Pi is the most common example.

  • M.2 and Half-size mPCIe Cards Support Real-Time Ethernet and FieldBus Networks

    Hilscher cifX M.2 and half-size mini PCIe cards powered by the company’s NETX 90 network-on-chip multi-protocol Cortex-M4 SoC bring real-time Ethernet and FieldBus to compatible systems. The tiny cards are designed for PC-based devices such as IPC’s, HMI’s and robots, and support various firmware for PROFINET IO-Device, EtherNet/IP Adapter, EtherCAT Slave, or OpenModbus/TCP. The company claims its cifX M.2 (A+E key) and half-size mini PCIe cards are the smallest multiprotocol PC cards on the automation market with a size of 22×30 mm and 30×26.8 mm respectively. The cards also support extended temperature from -20°C to 70°C and offer one hardware platform for all real-time Ethernet slave protocols. Besides PROFINET IO-Device, EtherNet/IP Adapter, EtherCAT Slave, and OpenModbus/TCP, Hilscher will provide support for CC-Link IE Field Basic and Ethernet POWERLINK Slave in new firmware available in Q4 2020, and OPC UA and MQTT functionalities are planned for future releases.

  • EMIT ESP32 IoT Development Board Comes with Temperature & Humidity Sensor, 5A SPST Relay (Crowdfunding)

    ControlBits EMIT (Environmental Monitoring for the Internet of Things) is a baseboard compatible with DOIT ESP32 DevKit V1 development board and equipped with a temperature and humidity sensor, a relay, a 12-pinGPIO connector, and a MicroSD card.

''4 Best Lightweight Linux Distros to install on USB Drive for Portable OS

Well, it doesn’t mean the only scenario one requires one of the best Live USB bootable Linux distros when he or she needs to use the computer that is not trustable. There are other situations as well, such as your current system is running Windows and you don’t want to have dual boot on your system, and still want to try out Linux? Then use the USB running Linux system. One of the main reasons that make Linux Distro an extremely portable operating system is the low consumption of RAM, depending upon the OS version or GUI, and support to run in a Live environment. This also beneficial for testing, preparing, backing up, or handling drive of the system that are crashed somehow… Furthermore, the machine without a hard disk can also be used with USB drive Linux OS Although we can install any Linux distro on a USB drive, however, here we will show the best open-source Linux distributions that are light in weight, consume less RAM, and other hardware resources to become a perfect portable OS option for Pen drives.

  • SUSE Addresses “ZeroLogon” Vulnerability

    On September 11, Secura research published a new software vulnerability called “ZeroLogon”, which exploits a protocol weakness in the SMB Netlogon protocol. This vulnerability may affect users of SUSE Linux Enterprise Server running Samba servers in older or non-standard configurations. Attackers could use it to bypass access control to the domain controller.

  • Digest of YaST Development Sprint 108

    In our previous post we reported we were working in some mid-term goals in the areas of AutoYaST and storage management. This time we have more news to share about both, together with some other small YaST improvements.

  • Modules and dev kits run Linux on 2.3-TOPS equipped i.MX8M Plus

    Variscite’s “VAR-SOM-MX8M-PLUS” and smaller “DART-MX8M-PLUS” modules run Linux or Android on NXP’s AI-enabled i.MX8M Plus with up to 4GB LPDDR4, 64GB eMMC, WiFi/BT, and optional dev kits. Variscite has launched some of the first embedded boards to support NXP’s i.MX8M Plus, an up to quad-core, Cortex-A53 SoC running at 1.8GHz and equipped with a 2.3-TOPs Neural Processing Unit (NPU). Variscite’s VAR-SOM-MX8M-PLUS and DART-MX8M-PLUS modules join TechNexion’s Wandboard IMX8M-Plus SBC and the Wandboard IMX8M-Plus EDM SOM module that powers it. Toradex, meanwhile, has teased an upcoming Verdin iMX8M Plus module.
