Dragino LoRa programming for multiple sensors (LG01-P)

I'm a beginner for Arduino. I need to implement a LoRa project that use LG01-P. I can easily find the sketch that send DHT11 data to thingspeak. I have totally no idea on how to modify the sketch and upload data from MULTIPLE sensors as I only have little programming knowledge in Arduino. Anyone can give advise on how to modify the dht11_server and dht11_client so that I could upload more than 1 sensors' data to thingspeak. Really appreciate if someone can provide guidance for me.

Now imagine you're an average forum reader that knows nothing about your project.
Read your post with that in mind - you will realise it makes little sense, and offers no leads on solutions to your problem.
Next please go and read the sticky and using the your freshly gained insights try asking again.

I only have little programming knowledge in Arduino

That is easily fixed. Start by working your way through the simple examples that come with the Arduino program development software, to learn the language and the special features of the Arduino.

Blink an LED without using delay, read a voltage, a switch or a sensor, and away you go!
