I have connected the SDA from the sensor to D2 on the board and SCL from the sensor to D1 on the board. But all I'm getting is: "HTU21D, SHT21 sensor is faild or not connected", when I run the HTU21D_Demo.
When I run I2C scanner (link) it finds an I2C device at address 0x40 and nothing when I remove the sensor. So I guess the sensor is wired up correctly and there might be something else I am doing wrong/missing.
Hello
I am using the Wemos D1 mini Pro and a SHT21 sensor (identical to this one:).
I have connected the SDA from the sensor to D2 on the board and SCL from the sensor to D1 on the board. But all I'm getting is: "HTU21D, SHT21 sensor is faild or not connected", when I run the HTU21D_Demo.
When I run I2C scanner (link) it finds an I2C device at address 0x40 and nothing when I remove the sensor. So I guess the sensor is wired up correctly and there might be something else I am doing wrong/missing.
Hope you are able and willing to help me
