The example code SHT4test is using 115200 baud rate. Have you set your Arduino serial console to that speed? I know the screenshot in the guide shows 57600, but that is not correct.
Code: Select all
/***************************************************
This is an example for the SHT4x Humidity & Temp Sensor
Designed specifically to work with the SHT4x sensor from Adafruit
----> https://www.adafruit.com/products/4885
These sensors use I2C to communicate, 2 pins are required to
interface
