The FlowGo Interface
DO96 (4)
In the
Go
program select
Set Interface Sensors
from
the
Settings
menu.
Click on the down arrow next the appropriate sensor input
number and select the sensor type from the list. Click on
OK.
Go
can decide whether or not to carry out a command or run a procedure
according to the value from the sensor.
Is the value
from the
sensor greater
than 20?
Is the value
from the
sensor less
than 50?
Pre-assembled analogue sensors are available from Data Harvest.
If you wish to assemble your own the connections to the 3.5 mm Stereo Jack Socket
are as follows:
A
C
B
A = 0 V Ground
B = V. Ref.
C = Signal
To ensure that 'home-made' sensors respond correctly to the calibration tables found
in
Go
, they should be built to the following standards:
Light Sensor
ORP12 (LDR) between V Ref. (B) and Signal (C)
2K7 Resistor between Ground (A) and Signal (C)
Rotational Sensor
10 K linear pot, track legs to V Ref. (B) and Ground (A),
Wiper leg to Signal (C)
Temperature Sensor
100 k 6A1 Thermister bead between V Ref. (B) and Signal (C)
100 k Resistor between Ground (A) and Signal (C)
The sensors are driven from a single reference voltage of 2.5 V, which can provide
up to 3 mA of current for each channel.
