TOSR02-T - 2 Channel USB/Wireless 5V Relay Module
(Temperature Sensor Support )
Can work with XBEE or Bluetooth Bee or Wifly Module


Last items in stock


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 USB bus or DC power 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 TOSR02 is here: G5LA datasheet

If you use DC Power ,the Input voltage should be DC5V.

First Step - Install the Driver
The TOSR02-T module uses FT232RL USB to UART chip . Before using the TOSR02-T you will need to download the FT232RL Driver.

Connect the TOSR02-T and windows will detect it and ask for the drivers. Point windows to the inf folder and it will install the driver.

The TOSR02-T will now appear as a com port.

The TOSR02-T operates with an easy to use command set as described in the table below.

TOSR02-T Baud rate : 9600 

Test program
To get the TOSR02-T up and running in the minimum amount of time we have put together an example program to demonstrate the functionality of the module.
