CS115 Barometric Pressure Sensor

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.
