Bricks

You want to capture data which are out of reach from the TMOR base station? The solution would be to use a brick module. With the brick module you overcome wider distances than wifi, as it uses the Xbee protocol. You simply add two XBee radio modules, one to the base station, one to the brick, program them accordingly, and register all the newly connected sensors to the brick at the base station. Or you purchase our TMOR extended plan and every thing is readily set up for you. You only need to switch it on.

1-wire sensor generals

We successfully test up to 8 DS18B20 1-wire temperature sensors connected to the base station. The current Brick supports one DS18B20 1-wire temperatur sensor. The here depicted DS18B20 1-wire temperature sensors are water proof. The wire coloring of this sensors is as follows:
- Yellow: GND (Ground)
- Green: SIGN (Signal)
- Red: VCC (Supply voltage)
Note: Seperatly purchased 1-wire sensors might have a different wire color coding. It turned out to be of good practice to note the address of the sensor on the sensor itself by using a sticker.

IO input ports - Digital and mechanical switches

We support the connection of digital and mechanical switches. Mechancal switches come in handy to capture movements such as opening and closing doors and windows.
For the time being only the Brick provides IO ports. Each brick supports up to 4 IO ports. The address of the input ports is:

• D0
• D1
• E6
• E7

The brick direct rule needs to be configured to make use of the digital input ports.

Analog input ports

The analog ports are ideal to capture contimous values such as light intensity or humidity. The analog input ports are in a basic version implemented but not fully supported yet. In order to measure analog data you need to have a brick. The analog ports are labeled as:

• ADC1
• ADC2
• ADC3

The analog input ports provide a potentiometer to adjust the operating point of the analog digital converter. The resolution of the analog input port is 2^10 - e.g. the numerical values are between 0 and 1024.

Digital output ports

The output ports or aka actors can change the status of an output port. The analog ports are labeled as:

• PB0 (PIN 10) RED LED
• PB1 (PIN 11) YELLOW LED
• PB2 (PIN 12) GREEN LED with 5V power driver

The port status can be changed manually or via the two rule engines (rule engine and brick direct rule engine).
