Frequently asked questions
Can I use the SHT31 module with Arduino or ESP32?
Yes. Connect SDA and SCL to the board's I2C pins. For ESP32, which uses 3.3 V logic, power the module from 3.3 V unless the breakout includes level shifting.
Can two SHT31 sensors share the same I2C bus?
Yes, if the module exposes the address pin. The default address is 0x44, and pulling the address pin high selects 0x45, so two sensors can coexist on one bus.
