How does it work?

The best technology the community has to offer.. hidden from view.

← The main controller

The beating heart is designed to be hidden, for example, inside a fake candle.

Create a network of sensors →

Measure and control light, temperature, air quality, electricity, and so much more. We like hiding them in books.

The main controller

Go beyond the glowing blue orb. For example, by hiding it inside an LED candle. It can act as a normal light, or notify you of the system's status.

Temperature, humidity and weather sensor

Measure temperature, humidity and air pressure over time. The air pressure allows the system to predict the weather, like an old school barometer. No need to connect to the internet for the weather prediction anymore!

The BME280 sensor

It's amazing what such a small thing can do!

This tiny sensor measures temperature, humidity and air pressure, all in one.

TIP: Why not organize a workshop, and create a large network or sensors in your neighbourhood.

Connecting the sensor

1First create the base sensor.

2The BME280 has 4 pins that you'll need to solder on. Two pins are for power, and 2 for the data signal. Connect..

  • CLK pin 8
  • DATA pin 9

3Finally, upload the code to the node.

The code

The code is open source; you are free to use, modify and share it.

Electricity sensor

Measure how much electricity your house uses by counting the little light pulses that your meter gives off every few seconds. The more power you use, the faster this light blinks. Count the frequency, and bingo.

The photo diode

The little LED at the end of this board is actually a photo sensitive diode. It can respond really quickly, which allows it to detect the light pulses.

Use some tape or other construction to place the photodiode in front of the blinking light, and make sure not other light can interfere with the counting.

TIP: The sensors automatically form a 'mesh network': they pass along messages, so vast distances can be crossed.

Connecting the sensor

1First create the base sensor.

2Use 4 wires to connect the sensor to the base:

  • CLK pin 8
  • DATA pin 9

3Finally, upload the code to the node.

If necessary, tweak the diode's sensitivity by using a tiny screwdriver and turning the little metal knob.
