Hello, i'm using a ESP vroom 32 and i connected a Si7021 humidity sensor on the I2c interface but i can't get i work. I need to use the Adafruit library and not another one. My problem is that the monitor is empty when i launch the example sketch. The sensor is detected at 0x40 with an I2c scanning sketch. I also tested a BMP180 sensor on the same interface and it works fine.
Do you have any idea how i can solve this issue
Thank you
Try loading the Adafruit Si7021 library & then running the Adafruit Si7021 Demo sketch as shown HERE
HTH
It doesn't work even when i follow these instructions carefully. The serial monitor wil not display anything when i launch the Adafruit library sketch. But when i launch a non-third party sketch like the one below the si7021 works fine on the same interface.
How i can modify the adafruit library so i can make this sensor work ?
Thank you
Hi robrs it seems that the unique adafruit library working with my Si7021 sensor on Esp32 or Teensy seems to be this one :
I tested this lib with its example and it is ok with it
Actually my sensor has multiple references, Si7021, HTU21 ans SHT21.
I found an Adafruit library for HTU21 and it works fine.
Thank you
