/*! * @file  DFRobot_SHT20_test.ino * @brief DFRobot's SHT20 Humidity And Temperature Sensor Module * @n     This example demonstrates how to read the user registers to display resolution and other settings. *        Uses the SHT20 library to display the current humidity and temperature. *        Open serial monitor at 9600 baud to see readings. *        Errors 998 if not sensor is detected. Error 999 if CRC is bad. * Hardware Connections: * -VCC = 3.3V * -GND = GND * -SDA = A4 (use inline 330 ohm resistor if your board is 5V) * -SCL = A5 (use inline 330 ohm resistor if your board is 5V) */
