SONOFF TH - request for schema of wires connection of Dupont - 2.5 mm jack connector


I got my SONOFF TH10 together with AM2301 sensor.

I managed to connect SONOFF TH10 device to WiFi and register in in eWeLink software.

But it turned out that my AM2301 sensor does not work, I get 'Failed to read sensor data' error in the app.

I disassemled the sensor and connected it directly to my Arduio board (without 2.5 mm audio jack).

It turned out the sensor works proper itself.


The next step, I checked each wire of 2.5 mm jack connector. I pinged each wire using multimeter and it turned out black wire connected to VCC is broken, please find attached printscreen.


Could someone confirm if wires are placed properly in the connector, in the same way as I have them in my devvice?

Many thanks in advance!

Best regards,
