The sensor pins can be automatically sampled and data forwarded in 2 modes:
to enable the above modes, use the
set q sensor <mask> command.
For example, to sample all sensors inputs, use the set q sensor 0xff command.
WiFly modules contain an onboard Sensor power pin, which is controlled by the command below:
set q sensor <mask>
set q power <value>
17.1. Automatic sampling of sensor pins:
1. the UDP broadcast packet will contain the value of the samples.
2. in HTTP mode, the pin sampled data can be forwarded to a remote server
17.2. Using the Built In Sensor Power

The power is removed immediately after the sampling is complete.
The values used for setting the power are described in the table below:

sensor power. This is a 8 bit register with two 4 bit nibbles. If the top
nibble is set, then power is applied upon power up and removed upon
power down or sleep.
If the bottom nibble is set, then power is applied when a sampling event
occurs, for example:
This is a new register added in ver 2.23 to automatically turn on the

Bitmask value that determines which sensor pins to sample when sending
data using the UDP broadcast packet, or the HTTP auto sample function.
