ARDUINO Wireless 868MHz


Wireless Actuator composed by a GATEWAY unit (Arduino shield) and by one or more ACTUATOR units with the possibility to switch from a minimum of 4 up to a maximum of 256 devices (relays). This wireless control system is designed for the most varied requirements in the field of Home automation, it can be used to activate all kinds of lighting, as other applications, for example heating / cooling, electric gates, automatic doors and industrial controls. The GATEWAY unit is controlled by ARDUINO microcontroller. It is possible to have a "point to point" configuration (No.1 GATEWAY unit - No.1 ACT unit) or a "point-multipoint" configuration (No. 1 GATEWAY unit more ACT units ) up to the possibility of switching 256 users (relays ).


RCQ3-868-ACT Actuator board


This board allows to drive 4 relays both in monostable and bistable mode. It is possible use commercial relay board. Must be powered at 5Volt.




The GATEWAY unit is composed from an Arduino shield that allows to transmit simple Rs232 command through ARDUINO microcontroller.
On the Radiocontrolli website you can find some example of Arduino code.


Main characteristics :


- Bidirectional systems

- Sending via Rs232 of a switch command to the ACT unit, to switch N.4 relay in monostable or bistable mode.

- For each switch command sent the Gateway receive a feedback from the ACT.

- It is possible to know the state of the individual relay of a specific ACT unit anytime.

- It si possible to manage more ACT unit.

- Request the RSSI value

- Request the remote configuration and remote battery value.

- Request the remote Temperature value.


Actuator Board + Relay Board

Gateway (Duino Board)

The main features of this bidirectional system are:


1) Sending via RS232 of an actuation command to one or more actuator card to actuate the 4 relays.

2) At each actuation command the actuator device sends the feedback relating to the operation performed.

3) It is possible at any time to know the status of the individual relays of a specific actuator card.

4) The relays can be managed in monostable mode and in bistable mode

5) Each actuator has a temperature sensor on board and it is possible to send a command, to know the temperature value of the individual


Command Sent from RS232
Set the Output "x" to Low Level ("x" can be 1,2,3,4)
Set the Output "x" to Low Level ("x" can be 1,2,3,4)
Request Monostable or Bistable State
Request Output State
Request RSSI value
Request remote battery Value
Request Temperature Value
Request remote Configuration
Request Software version

For each device (gateway and actuator) it is necessary to set the following parameters:

- LOCAL ADDRESS: Device address

- DESTINATION ADDRESS: Address of the device to which you want to


Each device is preconfigured with a default address "7E 7E 7E 7E" this address can be changed or via RS232 commands.
