0-1 Volt adaptor

The 0-1 Volt adaptor allows sensors which produce an output ranging between 0 and 1 Volt to be used with Smart Box. The adaptor amplifies the signal to give the normal Smart Box input range of between 0 and 2.55 volts.

Connection to the adaptor should be made using standard 4mm plugs. When the adaptor is connected to Smart Box the appropriate input will be labelled ‘Adaptor’.

Typical use

The following example shows how the adaptor can be used to connect a Philip Harris Blue Box Light Sensor to Smart Box.

• Plug the adaptor into one of the analogue sensor sockets on Smart Box. The Smart Move software will rename the appropriate input ‘Adaptor’. This default label can be changed as detailed later.
• Connect the Black socket on the sensor to the Black socket on the adaptor using a lead with 4mm plugs.
• Connect the Red socket on the sensor to the Red socket on the adaptor.
• Switch the sensor on.
• The Smart Move screen display will now show the current reading from the sensor. The sensor can be used in the same way as any other Smart Box sensor. The light level can be displayed using the PRINT command eg. PRINT ADAPTOR.

Renaming the sensor

The default name 'Adaptor' can be changed using the LABEL command as follows:

• Type as a direct command

LABEL ADAPTOR LIGHT

The sensor can now be referred to by the name LIGHT. For example PRINT LIGHT will now display the current value from the sensor in the output window.

Calibration

The calibration information supplied with the sensors can be used with Smart Move. Smart Move will display a full scale reading (255) when the sensor produces 1 volt of output. The table below shows the data for the Blue Box Light Sensor with the value that Smart Move will display alongside. This value is simply obtained by multiplying the Output Voltage column by 255.

Output Volts	Light Level Lux	Smart Move reading
0	1	0
0.2	10	51
0.4	100	102
0.6	1000	153
0.8	10000	204
1.0	100000	255
