In other words, all of the sensors on the shield can be accessed by calling the command line ENV.readSensor() where readSensor has to correspond with the actual sensor being checked. You can call this method through the object named ENV that is built and exposed when instantiating the library.
KILOPASCAL, sensor returns data in kilopascal, this is the default option. MILLIBAR, sensor returns data in millibars. PSI, sensor returns data in Pound per Square Inch. The library exposes the sensor with the method readPressure() which can take either no parameters or one of the following three, that will determine the units in which pressure will be expressed: It is a sensor manufactured by ST microelectronics. The ENV Shield has a barometric pressure sensor called LPS22HB. The building configuration is simple to mount and keeps the components secure.įigure 3: ENV Shield highlighting the pressure sensor We recommend that you mount the three boards together from now and keep them this way throughout the course. This is something we will not see throughout this course, but you should be aware of the possibility. The shield has a prototyping area that could be used to solder your own components and, in that way, make a more final installation using it. Activating the relays is as simple as activating one of the pins that control them, this will allow for electricity to flow. The MKR Relay Proto Shield is a board providing your MKR1010 board with two relays, which are electromechanical switches, that can be used to control any kind of electrical devices that could be activated with an on-off switch: lamps, fans, water pumps, electrical motors, heaters, etc. #United sketch fritzing how to
Follow this step-by-step guide in how to install any library, choose the needed ENV Shield library by typing its name in the search box, it will give you access to the different sensors in the shield.

The software the allows using a certain shield is what we call a library. These new features come with associated software you will need to install. This could be handy when designing systems that might not be connected or where the data gathering happens at such a pace that it is not possible to send all of the data through the network because of bandwidth issues.
This can be used to store the data gathered by the sensors locally. The ENV Shield comes with a microSD card slot. The different sensors communicate with the MKR1010 using either the SPI or I2C protocols, standard communication mechanisms within electronic circuit boards. The ENV Shield comes with the following sensors:

You can also start using the online version of Arduino’s code editor that you will find at: Please note that you have to become a registered Arduino user to use the online editor.Ī shield is a board that you add to an Arduino microcontroller board to add some extra functionality.
#United sketch fritzing Offline
You can use that guide to install the offline Arduino IDE that will run from your computer, and to learn how to troubleshoot any potential issues you might have when writing your first programs. You can see how to connect this board to your computer by checking this Getting Started Guide. We will see some of those features in action in this collection of exercises.
#United sketch fritzing Bluetooth
The Arduino MKR1010 (read “maker ten ten”) is a microcontroller board featuring a chip that will allow you making either a WiFi or Bluetooth wireless connection to other boards or computers. This exercise requires having previous knowledge in:
Learning about barometric pressure sensors. Creating files in the SD card, reading them in the computer. All of those scenarios are supported by the use of the SD card slot in the ENV Shield, the only thing you will need is a micro SD card. There is also the situation when you want to have a local backup of the data in case the communication fails at any given time. It could also be the case when you can only transmit small amounts of data in real time, but you are interested in collecting as much as possible for a later in-depth study. There are scenarios where it is not possible to send the data to a different location via WiFi or Bluetooth (as you could do with the MKR1010), but you are still interested in collecting data for offline analysis. In this case we will introduce the remaining sensors in the shield: barometric pressure, and different types of light radiation, collect data from all of the sensors and store it in a file inside an SD card for later analysis. This experiment will introduce you to the use of SD memory cards with your ENV Shield to store data into files that you can later transfer to your computer and use as explained in the previous experiment.
