• How to build temphum ?

temphum is an USB temperature/humidity sensor.
You can optionally add a photoresistor to measure light.

A version with a small display will be available later.

There is a example of a widget here http://madnerd.org/interface/temphum

• Go to libreInterface
• Import apps/libreInterface/dht11.json
• Modify the code

All modifications made using the developer console will be saved.
Go to http://github.com/madnerdorg/libreinterface for more information.

• Copy arduino/libraries into Arduino Sketchbooks folder
• Upload arduino/temphum/temphum.ino
• Test your sensor on http://madnerd.org/interface/temphum

To add the photoresistor change this line in the arduino code

const bool hasPhotoResistor = true;

• Arduino nano CH340G: 2€
• DHT11 : 2€
• Resistor pack 400pcs (3€) (1 resistor: 0.0071€)

Total : 6€ (4€)

You need to add a 4,7kΩ resistor between 5v/pin 2.

• Arduino - 2 : DATA (2)
• Arduino - 2 : RESISTOR (4,7kΩ) --> VCC (1)
• Arduino - 5v : VCC (1)
• Arduino - GND : GND (4)

/info -------> Give name:port

temphum:42004

Once /info is sent , the device will send humidity(%);temp(°c) or humidity(%);temp(°c);light(/1024)
