Intel Quark D2000 Environmental Sensors Board

Sergey Kiselev created this small board, equipped with a low power Intel Quark D2000 microcontroller and several sensors:

Intel Quark D2000 Environmental Sensors Board

The board can be used to monitor the environment conditions, and store or transmit the data to a remote system for further processing.
The Intel Quark D2000 microcontroller contains:
  • 32-bit x86 processor core
  • 25 GPIO pins
  • Support for UART, PWM, I2C, SPI, JTAG
  • 32 KiB of the instruction Flash ROM
  • 8 KiB of the SRAM
The on-board sensors include:
  • Accelerometer and Magnetometer
  • Atmospheric Pressure, Humidity and Temperature Sensor
  • Ambient Light Sensor

PiAQ: Open Source Indoor Air Quality Sensor

UPDATE 2016-10-24: Dave Conroy of CRT Labs will present the PiAQ tonight at Chicago hackerspace Pumping Station: One


National Association of Realtors’ CRT Labs in Chicago has developed a Raspberry Pi HAT to make information about the air people are breathing more accessible:


The PiAQ

Open Source Indoor Air Quality Sensor for Raspberry Pi

Measurement Points:

  • Temperature (SHT31)
  • Relative Humidity (SHT31)
  • VOC (Volatile Organic Compounds) (IAQ Core)
  • Derived CO2 (IAQ Core)
  • Barometric Pressure (MPL3115A2)
  • Light Intensity (TSL2561)
  • CO Concentration (MiCS-4154)
  • NO2 Concentration (MiCS-4154)
  • Sound Intensity (ADMP401)



  • FSK (RFM69HW 433/915MHz)

Garage Parking Sensor Board

Chip McClelland created this visual aid for parking in a two car garage:


Garage Parking Sensor Board

Let’s face it, garages are simply never big enough. There is always more you want to put into a garage than will fit and once you park your cars, things get tighter still. To get the most out of this space, your car needs to be parked correctly everytime. That is what this little device seeks to do.

Atmel SAMD21G Sensor Board

Mike Rankin created this tiny sensor board with an ARM Cortex M0+ microcontroller and OLED display:


0miker0’s Blog: SAMD21G Sensor Board

It’s pretty tiny so a 4 layer board made the whole job easier. The top and bottom are pretty much dedicated for components, layer1 are tracks and power traces, layer2 is a ground plane. Mixing up an internal plane and routing layer was interesting.

The hardware consists of:

  • SAMD21G18A processor (used in the Adafruit Feather)
  • HDC1080DMBT temperature/humidity sensor
  • ADXL345B accelerometer
  • DS1340U RTC
  • MCP73833 LiPo battery charger
  • MicroSD card connector
  • Navigation Button and pushbutton
  • 0.66″ mono oled display
  • Micro USB connector for charging and uploading new sketches


The design files and source code are available on GitHub:

Monitor plants with Bluetooth LE

JamesCannan created a simple way of monitoring plants with Bluetooth Low Energy (BLE):

Easy Planter

Monitor temperature, humidity, pressure, moisture, light, and has I2C extension pins so that you can add other modules. Information is sent to a phone, and notifies you when it needs something.
