You may be worrying about what you should do when you encounter communication problem with our sensors and how we can help you.

Firstly, let's figure out what  data transfer unit(DTU) is.

A data transfer unit commonly have RS232 and RS485 interface, as well as RJ45,WIFI, 3G/4G/ NB-IoT,Lora transmission interface.

Lora is sort of radio communication, it's very suitable for point to point communication or broadcast communication.


Guidelines belowe show you how we can use a WIFI DTU to realize transparent data transmission.

Such DTU is available at rough cost of 40 USD/UNIT/FOB CHINA.

Following steps will connect this DTU to our cloud server.

1. We will set it work in mode of STA, and pre-configure a default WIFI hot spot which it will connect to.

2. Thereafter, we pre-configure DTU as TCP/IP client, and input the globally unique IP and TCP/IP Port of our cloud server.

3. What you need to do is creat a WIFI hot spot according to the ID and password we provide you.

And then power up our sensors and DTU, correctly connect our sensor output to the input of DTU.

4. Now we are able to remotely access the sensor connected to this DTU, draw me an email or make a call, I will be at your service and diagnose our products remotely for you.

With realization of such data connection, there are various of after-sale service we can provide  you with.

DTU is very useful in my opinion, what do you think of it?
