Telemetry is the automated sensing, measurement of data, and control of remote
devices. The emphasis is on the transmission of data from devices to a central control point.
Telemetry also includes sending configuration and control information to devices.
MQ Telemetry connects small devices by using the MQTT protocol, and connects the devices to other applications by
using IBM MQ . MQ Telemetry bridges a gap between devices and the internet making it
easier to build "smart solutions". Smart solutions unlock the wealth of information available on the
internet, and in enterprise applications, for applications that monitor and control devices.
The following diagrams demonstrate some typical uses of MQ Telemetry:
Telemetry: Smart Electricity
MQTT message containing energy usage data sent
to service provider.
MQ Telemetry sends CONTROL COMMANDS based on analysis of
energy usage data.
A simple card transaction is sent to the bank's server.
MQ Telemetry identifies the one person from the
thousands, alerting the customer that their card has been used.
MQ Telemetry can use the simplest input of information,
and locate that individual.
The use cases described in the subtopics are drawn from actual examples. They illustrate some
ways of using telemetry, and some of the common problems that telemetry technology must resolve.
