The friendly cloud sensor

Posted by René on October 14, 2014

This year, there was another Makelight competition. My contribution was an open-source cloud sensor, based on an Arduino UNO.

The Hardware

The project uses very basic components:

  • Arduino UNO
  • Wireless SD shield
  • IR sensor MLX90614
  • Light sensor TSL237
  • Temperature sensor DS18B20
  • 3x 4.7kOhm
  • 1x 100nF

Wolki hardware I milled a PCB and soldered all sensors on it.

The Software

I uploaded the software to github. The Arduino sketch is called DIY_SQM_Test_RAW.ino

Wolki software The Arduino sketch reads the sensors and sends it to the serial port.


For German instructions, please download this PDF.

I will add more details later.
