===== Light Sensor ===== {{ ::si1145.png?800 |}} We will use the [[https://learn.adafruit.com/adafruit-si1145-breakout-board-uv-ir-visible-sensor/overview|Adafruit_SI1145]] library to interface with the sensor. Unzip the content of this {{::adafruit_si1145.zip| zip file}} into the //Arduino\libraries// or use Arduino IDE's Add ZIP Library command. Now that we know how to measure a lot of parameters, let's learn how to use the radio interface to [[tutorials_radio| send data]]!
