Easy IoT Weather Station With Multiple Sensors

Ingenerare @ instructables.com show us an easy to build IoT weather station able to measure temperature, dew point, humidity, pressure, light index, and rain. He writes:

A weather station is a fun project that teaches you a ton about electronics with the added benefit being an actually useful little device. The project requires a bunch of cheap parts and sensors totaling less than $15, and the whole thing ends up fitting in your hand. The station creates a web site that monitors temperature, dew point, humidity, pressure, light index, and rain (Thingspeak channel). It’s a pretty easy set up, and you’ll just need some basic electronics skills to get it going.

Early Diagnosis Now Possible With Smart Bandage

IoE era is here since we are able now to add mobile radio capabilities in our applications! The latest incarnation of the cell phone network will offer internet connectivity and possibilities that could only be dreamt of previously depending on your standpoint, and many more factors.

And now let’s embed these concept in medical applications, like “Smart Bandage” . It is conceivable that sensors embedded in a medical dressing could continuously monitor the wound healing process and send alerts to medical personnel when an infection is detected.  Maybe the patient could not tell accurately  since the pain is not a valid indicator of biological dysfunction. The problem is that we all have different thresholds; some stalwarts may endure the pain and only end up visiting a doctor as a last resort when the simple infection has developed into something nastier. Other patients will be convinced that a slight twinge is evidence of a life threatening condition. An objective assessment of the patient’s state of health will not only be reassuring to the patient, but also lead to a more efficient use of medical resources and reduced health care costs.

For this reason, band-aids with sensors and 5G network interfaces seem like a win-win formula. They will give the doctor an early indication of problems and may even be able to run rudimentary diagnostics to indicate the cause of the problem. Instead of long waiting times for appointments and expensive laboratory tests we could, for example get an immediate recommendation of an effective antibiotic. This is just one small example of the many benefits that the IoE will eventually bring to medical care in the future.

“That intelligent dressing uses nano-technology to sense the state of that wound at any one specific time. It would connect that wound to a 5G infrastructure and that infrastructure through your telephone will also know things about you – where you are, how active you are at any one time. You combine all of that intelligence so the clinician knows the performance of the specific wound at any specific time and can then tailor the treatment protocol to the individual and wound in question.” – Prof Marc Clement, chairman of the Institute of Life Science (ILS).

$10 Orange Pi 2G-IoT Competing With Pi Zero W

A new competitor to Raspberry Pi Zero W is just out! A new single-board computer by Orange Pi that is now available at AliExpress is competing against Pi Zero W, the Orange Pi 2G-IoT. Using this powerful SoC you can build a computer, a wireless server, games, musics and sounds, a speaker with Android, Scratch and a lot of other options since Pi 2G-IoT is open source.

The Orange Pi 2G-IoT has ARM Cortex-A5 32bit clocked at 1GHz with 256MB DDR2 RAM, 500 MB of on-board NAND storage to go along with an SD card slot for larger storage. It also has a CSI camera connector, WiFi, Bluetooth, an FM Radio and GSM/GPRS with a sim card slot on the bottom. It is pin compatible with Raspberry Pi’s almost standardized GPIO layout.

This $10 board is impressive especially the addition of GSM/GPRS, but it is not promised to kill other competitors in sales, even though it is a powerful little computer. Since the community of Raspberry Pi product is much more larger and more supportive, Orange Pi fails in engaging its audience with the products it makes.

Unfortunately, Orange Pi website is not updated yet to include its newest product. However if you are interested in getting one for yourself right now, head over to AliExpress to get your 2G-IoT for only $9.90 and to know more details.

Educational Biomed Shield for Arduino 101

Orlando Hoilett has built his new biomedical Arduino 101 shield: Biomed Shield, in order to allow students, educators, and hobbyists to learn about bio-medicine by monitoring heart rate, temperature, and other physiological metrics.

To build this shield he used the following components:

  • AD5933
  • MLX90614
  • Microchip Rail-to-Rail Input/Output Dual Op-Amp
  • MAX30101: a specialized integrated circuit that is able to perform reflectance photoplethysmography
  • Photocell
  • Thermistor
  • AD8227

Orlando measured heart beats using transmission photoplethysmography using MAZ30101, where a light shines through an extremity such as a finger and a detector measures the amount of light that passes through. When the heart pumps blood through the body,  a momentary increase in blood volume in the fingers happens. As a result, the amount of light that passes through the finger changes with this changing blood volume and is detected by the photodetector.

Bioimpedance Measurement

Bioimpedance is can be another class of bioelectrical measurements where we measure the impedance of the body instead of measuring the electrical signals produced by the body with the help of AD5934 impedance analyser chip. He is also measuring body temperature with the MLX90614 and measuring the amount of light using  a CdS Photocell.

Orlando built this shield for education purposes not as a medical device, and his work on this shield is still in progress. Follow his project on hackster.io to know more details and updates. You can check source files at Github.

Arrow’s New FPGA-Based IoT Maker Board

Arrow Electronics has introduced a new FPGA IoT Maker Board designed for end-to-end application development and optimised for cost. The Arrow MAX1000 board can be installed directly into a custom application or integrated on to a completely separate board.

It has been created for start-ups, universities or established equipment manufacturers who want a flexible, low cost FPGA platform for development, and the distributor can also supply customised variants.

At the heart of the maker board is a compact (11x11mm) Intel MAX10 FPGA with 8000 logic elements. This single chip includes integrated flash memory, a 1Msps 12bit ADC for analogue signals and a 3.3V power supply. Other features include embedded SRAM, DSP blocks, instant-on within milliseconds, and the ability to implement Intel’s NIOS II soft core embedded processor to perform microcontroller tasks. The board is equipped with an integrated Arrow USB-Blaster that enables the FPGA to be programmed directly from a PC and debugged using the free of charge Intel Quartus Prime Lite software.

The MAX1000’s power can be supplied as 5V from the USB port or via a separate pin. An Enpirion DC/DC converter with integrated coil then generates the 3.3V supply used on board. A MEMS oscillator provides the clock supply for the FPGA and the USB bridge. The low power, 3-axis acceleration sensor – also based on MEMS technology, can be used for position and motion detection, which are often required in IoT applications. External SDRAM can be used for storage of application data or as memory for the NIOS II processor.
