1. A method implemented by a low powered, integrated remote data acquisition platform in a distributed wireless monitoring system via a web-based program that comprising:
- a. receiving over the wireless internet link from the cloud server a predetermined difference threshold for event triggering and sampling interval;
b. sampling by comparators a sensed parameter(s) on a dynamically programmable sample rate;
c. activating a data logger when the comparators sense a differential change in the sensed parameter exceeding the dynamically programmable difference threshold for event triggering from a dynamically programmable baseline value;
d. compression encoding the stored data;
e. logging the sensed value together with a relative time by the data logger as stored data until the parameter returns to the dynamically programmable baseline;
f. receiving over the wireless internet link from the cloud server a dynamically configurable sensor calibration, sample rate, trigger threshold information, reporting schedule and current time and date information;
g. receiving over the wireless internet link from the cloud server dynamically configurable sensor calibration and trigger threshold information;
h. transmitting the compression encoded stored data over the wireless internet link to the cloud server according to the dynamically configurable reporting schedule;
i. receiving over the wireless internet link from the cloud server device control parametersj. sending control signals to actuators based on the received device control parameters.

Abstract
A distributed wireless monitoring system with low-power remote sensors includes data encoding/compression at sensors to reduce power use from transmission and storage (where the compact data representation is decoded after upload), event activated operation/data logging, remote configuration of event triggering thresholds and correlation templates, distributed processing capabilities, and sensor clock synchronization from a network time service.
