Hi, this is the case for the PandaTouch temp and humidity sensor.

You hace an I2C connector on the panda touch, so you can plug a temp and umidity sensor.

You need last firmware for panda touch : 

https://github.com/bigtreetech/PandaTouch/tree/master/Firmware/1.0.6.3

You can buy the DHT20 sensor on amazon or aliexpress

For the connection you need to connect sensor with the i2C port of the Panda touch, so :

SDA 1 → SDA

SCL1 → SCL

GND → -

3,3V → +

Have a Nice Print !!!
