TOSR02-T - 2 Channel USB/Wireless 5V Relay Module Temperature Sensor Support
Product Code: G525D497231976
Product Description

This USB/Wireless relay module allows your computer to control external devices turning ON/OFF via the computer USB port.

It also has a wireless extension port that can work with XBEE or Bluetooth Bee or Wifly Module, which means that you can now control your device via Zigbee or Bluetooth or WiFi !

The TOSR02-T module can powered by USB bus or DC power and provides two volt free contact relay outputs with a current rating of up to 10 Amp each.

It provides a DS18B20 temperature sensor port. You can use it to make a thermostat or any other similar applications.
Relay power rating

If the relay is used at a voltage or current exceeding the given 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 DC 5V.

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.
