TOSR08-T - 8 Channel USB/Wireless 5V Relay Module
(Temperature Sensor Support )
Can work with XBEE or Bluetooth Bee or Wifly Module
DC5V power supply 1A included




First,this USB/Wireless Relay Module allows computer control external devices ON/OFF via the computer USB port..

Furthermore, It  has a wireless extension port, can work with XBEE or Bluetooth Bee or Wifly Module, that mean now you can control your device via zigbee or Bluetooth or WiFi !

The TOSR08-T module can powered by DC5V power supply and provides four volt free contact relay outputs with a current rating of up to 10 Amp each.

It provides a DS18B20 temperature sensor portYou can use it make thermostat or any other similar application and so on.

Relay power rating
If the relay is used at a voltage or current exceeding this specification, the life of the contacts may be significantly shortened.

A full datasheet for the relays used on the TOSR08 is here: G5LA datasheet

First Step - Install the Driver
The TOSR08-T module uses FT232RL USB to UART chip . Before using the TOSR08-T you will need to download the FT232RL Driver.

Connect the TOSR08-T and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.

The TOSR08-T will now appear as a com port.

The TOSR08-T operates with an easy to use command set as described in the table below.

TOSR08-T Baud rate : 9600 

Test program
To get the TOSR08-T up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
