== Analogue input ==

The expected analogue input on pin 1 is between 0V and Vref (+2.55V) which will correspond to a reading of between 0 and 255 in the SmartMove software.

Each unit on the analogue input can therefore be said to correspond to 1/100V.

== Sense output ==

To identify the different types of Smart Sensor software on the Smart Box will drive the "Sense" pin 4 high approximately once per second. When the sense pin is driven high sensors should return a voltage corresponding to their sensor type to the Smart Box's analogue input. This can be implemented in your own sensors using an analogue multiplexer/demultiplexer (such as the 4053 IC) to switch between the sensor's output voltage when sense is low and the sensor's ID voltage when sense is high, e.g. produced by a trim pot between 0V and Vref.

=== Sensor IDs ===

There are 32 possible sensor IDs. The ADC reading mentioned in the table below is the minimum value that will cause the Smart Move software to identify a particular sensor, for example a humidity sensor can be identified with an ADC reading between 157 and 164.

Note that Smart Move 1.16 and Smart Move 1.18 have some different names for some sensors. If a space is left blank in the table then the sensor is treated as present but is labelled "SENSORA" to "SENSORD" instead of being renamed according to the sensor type.
