+ * @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)
