Sensor blocks

Sensor blocks are blocks designed to work with sensors. Before using a sensor block you must create the sensor first. Once the sensor are created a set of blocks appears in the toolbox to work with certain sensor features:

• The reading of a magnitude measured by a sensor is performed by a Reporter block. This block reports the value of a certain magnitude measured by the sensor, and in the sensor documentation is noted as "Read () from sensor".

  A shape example of a "Read () from sensor" block:

  

• Execute a script when a magnitude measured by a sensor changes. This is done by an Event block, and in the sensor documentation this block is noted as "When () changes from sensor".

• Some sensors can be configured. For example, you can configure the resistance values used by the voltage divider of a LDR sensor. The configuration values are set by blocks noted as "Set () with value () for sensor" in the documentation.
