Long range tele-control with CDT-01 module
Route markers for foggy roads
The markers blink to help drivers to stay on the road when the road is obscured with dense fog. All the markers must be turned on at the same time to show the driver the route. If the markers blink randomly, drivers cannot understand where the road is. The CDT module sends an 'On' signal by radio to all markers at the same time. This is an ideal application for CDT, in that a 1:N combination is easily achieved, along with long range transmission Route markers for foggy roads

Controlling reel for a hose
Controlling reel for a hose Spraying agricultural chemicals over crops with a hose in large fields in hard work.
Extending the hose is not particularly difficult, but winding it up requires a lot of work. CDT modules fit this application well.

The receiver receives On/Off control commands from the operator and starts the motor of the hose reel.
While the motor for pumping the chemicals is running, noise is generated by the motor. 
This creates an adverse environment for the use of radio. However CDT with a high tolerance for noise can be used safely in this sort of environment.
　
basic circuit
Most of the components for transmitting the On/Off signals are enclosed in the CDT-TX module. Practically the only additional external components required are switches. See the following basic circuit diagram.
