Introduction

No special technical skills or tools are required for this project. The result of this project is a fully functional broadboard with an barometric sensor and a display for displaying temperature, air pressure and humidity data of the BME280 Sensor.

The components are supplied with power via a micro-USB connection and can then be configured and used with the Sense App.

Connecting the bridge to the breadboard

Take the broadboard and bridge as shown and put the bridge on the red marked skirting boards. Please make sure that the USB port of the bridge is pointing downwards. The bridge must then be plugged into the pins labeled as follows:

– Left pin header: a: 16 to 30
– Right pin header: h: 16 to 30


Connect sensor module to breadboard

In this step, the sensor for temperature, air pressure and humidity is connected to the broadboard. The 4 pins are connected to j: 4 to 7. Make sure that the board is on the right and the pins on the left.


Connect the display to the breadboard

Now the display follows. The display will use the same cables as the sensor, therefore it shares all 4 rows with the sensor. The display must be aligned so that the pins are on the right. These are then plugged into the socket strips g: 4 to 7.


Connect sensor and display to bridge

Here the sensor and display is connected to the bridge. This supplies the sensor and display with power and connects it to the data pins D1 and D2 (I2C bus) of the bridge. For this a cable is plugged in as follows:

h: 6 to j: 17 (corresponds to label D1 on bridge)
h: 7 on j: 18 (corresponds to label D2 on bridge)
h: 4 on j: 21 (corresponds to label 3.3V on bridge)
h: 5 to j: 22 (corresponds to label GND on bridge)


Result

If your microcontroller (bridge) has not yet been loaded with the Sensate firmware, follow these instructions. Once this is done, the unit is fully functional and can now be used with the Sense App. Have fun!

To protect the components from dust and dirt, we recommend the installation in a plastic housing. This is possible even with little skill and equipment.
