Example Code for Arduino-Read Data

Hardware Preparation

• DFRduino UNO R3 (or similar) x 1
• SHTC3 Digital Temperature and Humudity Sensor x 1#
• M-M/F-M/F-F Jumper wires

Software Preparation

• Arduino IDE
• Download and install the SHT Library. (About how to install the library?)

   /*!
 * @file temperatureAndHumidity.ino
 * @brief Measurement of temperature and humidity
 * @n The sensor can be used to detect temperature and humidity within temperature -40~125 ℃ and humidity 0~100 %RH
 * @n The sensor supports four data measuring modes: clock stretching enabled, clock stretching disabled, clock Stretching Enabled & Low Power, clock Stretching Disabled & Low Power
 * @n Experiment Phenonmenon: measure temperature and humidity data every 1 second.
