I have two ESP8266-01 modules. I use one of them to upload data to my thingspeak channel directly from the DHT11 Sensor. So I can see temperature and humidty from the channel. Thats great I have no problem with that. But I am planning to use my other ESP module to show these datas in an LCD screen. I do not know how to retrive data from thingspeak channels. I would appriciate any help. I am using Ardunio IDE to program.

There are several examples in the ThingSpeak documentation to help you. The first example in the ESP section Post Temperature Data and Read from Channel provides code using the ThingSpeak communication library. If you don't want to use the ThingSpeak communication library, you can consider the Moisture Monitor with Deep Sleep. This one also shows how to put the device in deep sleep. These examples are specifically tested with NODE MCU devices (ESP-8266-12), but you can use the ESP-8266-01. Your device wont have an ADC which is used in come of these examples, and the programming process is slightly different, but it seems you already have the programming part down.
The Arduino code is similar, and you can look in the first section for more examples.
The first example with a sonar sensor and an Arduino MKR should port well to your ESP, with some changes. The others can give you some ideas as well.
