5.7 Light sensor
A light dependent resistor (LDR) measures light level and gives an analog signal that is
measured by the CC2430 A/D converter. The light sensor resistance ranges from 5KΩ (light)
to 20MΩ (dark).
5.8 I/O connectors
The I/O connectors bring out all the signals from CC2430. These connectors allow easy
access to all CC2430 I/O pins. External circuitry can be connected to these connectors for
prototyping.
