.  Hill Country Research Innovations in Telecommunication and Automation     Telemetry System

This telemetry system has many applications due to its versatile design.  It can be used as a handheld transmitter sending switch commands to a receiver controlling motors or relays.  Or as a remote data collecting device feeding temperature and humidity data to a computer screen. Or as an event transmitter signaling events along with an ID to a stand alone receiver (mailbox monitor).  Or as a  portable EKG monitor communicating with a home or hospital monitor.  Or as a robot controller streaming  PC data from a sophisticated control algorithm to a mobile robot.  Or as a timed remote controller for agricultural irrigation systems.  Transmitted analog data can be locally monitored through a special acoustic instrumentation system.

The range can be increased by adding one or more repeaters. The repeater microcontroller contains special software for forwarding of data.
