Ky-015 sensor on Raspberry Pi

Other Miscellaneous
1

I am trying to get the KY-105 Humidity and Temperature sensor to work on the Raspberry Pi. I have the same one on the Arduino Uno next to it. I know the wiring is right. I have the same sensor on the Arduino next to it. Tested this sensor on it.

Humidity read 0.0% on Pi. Temperature and Humidity work on Arduino.

https://github.com/szazo/DHT11_Python.git is the DHT11 file I am using.

I tested the single supply logic level data through ports with the LED Blink so all four pairs are working.

The 5V rail from the SSLLC is 4.97V

Using GPIO port 25. Checked the pin out on the T-Cobbler Pro. Tested Blink LED on it.

I tried an example with the AdaFruit KY-015 Git file.

Any suggestions?

Hello,

Is it really necessary to use the logic level converter? I mean, this sensor can directly be connected to the T cobbler plus, right?

Anyway, have you checked this tutorial? If you have not, you can give it a try. It contains many tips and tricks. https://www.freva.com/dht11-temperature … pberry-pi/

You can also cross-check your codes and circuit with this video to find if anything is missing.
