There are 4 inputs available to wake the module from sleep, SENS1-4.
To enable 1 of these inputs, use: set sys trigger <0,1,2,3,4>. 0 disables.
Only the SENS1 input has a resistor divider ( 24K in series with 10K to GROUND) which
allows this pin to tolerate 3V logic. The other sensor pins DO NOT, so care must be taken.
WARNING: Under no conditions should the voltage on any SENS2-8 input exceed
1.2VDC. Permanent damage to the module will result.
The SENS1-4 inputs have a small current source that is activated in sleep mode. This source
is approximately 100nA, and will cause the input to float up to about 1.2VDC.
IF SENSE1
for example, is enabled, pulling the SENS1 pin to GROUND will wake the device. An open
drain FET is a good device to tie to the pin. The threshold is about 500mV. Additional
