Dear sir  ., 

i like to know  to   which in i hvae to Connect DHT 22  or 11  in KC-868 -A4 1.2.5   borad , i used  pin 13  but  its cant able to reade

[admin]

do you using KCS v2 firmware ? or you config by ESPHome? or write your own arduino IDE code?
please write your question in details, so that can help you.

i am using  my own  aruduino  IDE code

GPIO13 is OK for DHT22. KC868-A4 board already include pull up resistance, make sure your DHT22 without pull up resistance. you can take a photo of your sensor. another way, you can download KCS v2 firmware , set DHT22 to use, test the hardware whether work well. if KCS firmware work well, then you should check your arduino code.

we are using GHT 22 and DHT without any pullup resistenace , Can i use another PIn number , please find the picture of sensor

maybe you should connect with 5V for your DHT22 sensor, NOT by 3.3v power.
please test by KCS v2 firmware firstly.
here is KCS v2 online guide: https://www.kincony.com/esp32-kcsv2-firmware.html

To confirm the above, most DHT22's won't run off the 3.3V output on the board so you have to take a 5V tap off the 433MHz connector. There's another thread somewhere that discusses this.

so i have told you, let KCS firmware to confirm firstly.
