Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi Measures VOC, Humidity, and Temperature

Renesas ZMOD4410 Indoor Air Quality HAT Raspberry Pi

We’ve recently covered a few products or solutions designed to report indoor air quality (IAQ) including ESPurna firmware getting support for BME680 precise indoor air quality measurements and Metriful Sense indoor environment monitor for Arduino and Raspberry Pi. Avnet has now introduced its own Raspberry Pi IAQ add-on board with “Renesas ZMOD4410 Indoor Air Quality HAT for Raspberry Pi” capable of measuring VOC (volatile organic compounds), humidity and temperature, as well as estimating carbon dioxide (eCO2) levels. Renesas ZMOD4410 TVOC Sensor Hat (AES-RHSEN-ZM44-G) key features and specifications: Sensor – Renesas ZMOD4410 TVOC / IAQ I2C sensor, Renesas HS3001 relative humidity & temperature I2C sensor Misc – Power LED; software-controlled status LEDs for “sample active” and “limit” Host Interface – 20-header for Raspberry Pi with configurable alarm/interrupt output Power Supply via header Jumper for supply voltage selection between 1.75V and 3.9V (default: 3.3V) Test points to measure ZMOD4410 current consumption Avnet […]

HeliOS is a Tiny Embedded OS Designed for Arduino Boards

Mannie Peterson (aka FellFromTree) has developed an embedded operating system called HeliOS that’s designed specifically for 8-bit and 32-bit Arduino boards, and can easily be used from the Arduino IDE. HeliOS is said to have only 21 function calls and implements cooperative and event-driven multitasking, task notification/messaging, timers, and memory management. It’s a non-preemptive multitasking kernel so you won’t have to deal with mutexes. The developer explains how scheduling works with HeliOS: HeliOS uses a run-time balanced strategy which ensures tasks with shorter run-times are prioritized over tasks with longer run-times. This ensures all running tasks receive approximately equal total run-time without using context switching. The other multitasking option available in HeliOS is event driven multitasking, which uses the wait/notify and timer interfaces. Mixing cooperative and event driven tasks in HeliOS is not a problem. To give it a try, simply open the Arduino IDE Library Manager, search for “HeliOS” […]

Folding@Home ARM64 Linux Beta Release for COVID-19 Vaccine Research

A few months ago, we reported that Rosetta@Home supported 64-bit Arm SBC’s and Servers in the Fight against COVID-19. But Folding@home did not support Arm hardware just yet, but thanks to work from Neocortix, Linaro, Arm, miniNodes, and Packet.com, we now get support for Folding@home on ARM64 meaning you can help researchers studying SARS-CoV-2 virus and help them develop a COVID-19 vaccine with Raspberry Pi 3/4 boards, or other 64-bit Arm SBC’s and servers. The solution relies on Neocortix Cloud Services Platform allowing the unused capacity of large numbers of individual mobile phones or other connected nodes to be harnessed into a single, unified computational engine. The very first application that made use of the platform was Neocortix PhonePaycheck were users get paid to let businesses perform calculations on their phones at night while charging and connected to WiFi. That way users of premium phones like Galaxy S10 or S20 […]

How to Fix Unreliable USB Hard Drives, Stalled Transfers in Linux

Last June, I reviewed a Ryzen Embedded SBC with Windows 10, and the USB hard drive I normally use for review had all sorts of problems including very slow speeds and/or stalled transfers but no error messages. Last week, I tried again by installing Ubuntu 20.04 on the same Ryzen Embedded SBC, and the USB hard drive had troubles again, so just assume there were some hardware incompatibility issues between the SBC and the drive, and there may not be a fix or workaround. Sometimes, it’s indeed a hardware issue with the drive getting too many bad blocks, and if that’s the case, and the drive is still under warranty you can return it and get a fresh new (or refurbished) drive for free. But that drive was still working with my laptop getting around 100MB/s. So I ran out of ideas until numero53 commented he had similar problems with […]

Zero Terminal V3 is a Modular Raspberry Pi Zero W Powered HandHeld PC

Zero Terminal V3 Raspberry Pi Zero W Handheld

Hardware hacker NODE has created a slick handheld Linux PC based on the Raspberry Pi Zero W board. About the size of a thick smartphone, Zero Terminal V3 also includes a touchscreen display, a built-in battery, a USB Type-A port, and a microSD card slot. The keyboard found in previous iterations of the Zero Terminal is gone, as the new version focuses on modularity thanks two 40-pin sockets that connect to the GPIO pins, video output, camera connector, USB ports, power indicators, etc… in order to allow people to create and add custom backpacks to change the functionality as needed. Zero Terminal V3 specifications: SBC – Raspberry Pi Zero W with Broadcom BCM2735 ARM11 processor, 512MB RAM, MicroSD card socket, WiFi 4, and Bluetooth 4.0 Display – 5.5″ 1080p AMOLED touchscreen display bought on Waveshare and designed for Raspberry Pi 3/4, but NODE designed an adapter for RPi Zero.
