CS115 Barometric Pressure Sensor
4
As you mount the sensor onto the backplate of the enclosure, place the fork lug
under the mounting screw to accomplish the proper grounding of the sensor as
shown in Figure 3-1.
3.3 Jumper Settings
The CS115 has two operating modes, ‘continuous’ and ‘triggered’. It is normally
shipped in the ‘triggered’ mode, in which the unit is turned on and off by applying
signal to the blue wire (EXT. TRIG.) using a datalogger’s control port. In this
mode, power consumption is minimized, but the sensor is subject to a 2-second
‘warm-up’ delay after it is turned on. You can also configure the unit for the
‘continuous’ mode to avoid the need for the delay, in which the sensor is powered
on continuously. This can be achieved either by connecting the blue wire (EXT.
TRIG.) to a continuous 1 to 24 VDC supply (to 5 V or 12 V channel of the
datalogger) or by changing the jumper position connecting the pins on the circuit
board. See Figure 3-2 below.
