TOSR08-T - 8 Channel USB/Wireless 5V Relay Module (Temperature Sensor Support )

Description: This USB/Wireless relay module allows a computer to control the switching of external devices by using the USB port of your computer.

It has a wireless extension port that can work with XBee or Bluetooth Bee or Wifly modules which means now you can control your device by Zigbee or Bluetooth or Wi-Fi.

The TOSR08-T module can be 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 also has a DS18B20 temperature sensor port. You can use it to make your thermostat or any other similar application by yourself.

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 TOSR0x 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.

Commands
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.

 The following images are examples that show how the temperature sensor is connected to the module.
