Urban Board¶
The Urban Board is a passive board that contains a selection of low-cost sensors for environmental monitoring, and a connector for a PM sensor. The measurements it takes depend on the version, but overall, it is capable of measurements such as:
- Temperature and Relative Humidity
- Barometric Pressure
- Noise Level and Frequency Spectrum
- Light (including UV-index after the 2.2 version)
- Air Quality Indicators (depending on the version)
- PM
The Urban Board has undergone several modifications throughout its development, and its current version is the V2.3. Below you can see all versions:
Assembly¶
The Urban Board connects to the Data Board with the connector labeled SENSOR BOARD:
PM sensor connection¶
Custom cable
Note that the PM cable, both for PMS5003 or the SEN5X, are custom made.
