Experiment: Detect Temp&Hum Values

  • Open the Arduino IDE and copy the following code into IDE, or select from the examples built into the IDE:
 File->Examples->_07_Sensor_Temp_Hum_AM2321->'read_simple'

#include <Wire.h>
#include <AM2321.h>

void setup() {
  Serial.begin(9600);
}

void loop() {
  readByAM2321();
  delay(500);
}

void readByAM2321()
{
  AM2321 am2321;
  am2321.read();

  Serial.print("(");
  Serial.print(am2321.temperature/10.0);
  Serial.print(", ");
  Serial.print(am2321.humidity/10.0);
  Serial.println(')');
}
  • Select the right board from Tools→Serial Port in Arduino IDE and download the program.

Program Debugging

  • The program uses AM2321 temperature and humidity collection library and defines "#include <Wire.h>" and "#include <AM2321.h>" as driving files.
  • The program uses two important libraries to communicate with the sensor. For any project/software that uses this sensor, the following libraries must be included:
    • For the AM2321 sensor: "#include <AM2321.h>"
    • For I2C Communication: "#include <Wire.h>"
  • “am2321.temperature/10.0”represents the calculated temperature value and " am2321.humidity/10.0" represents the calculated humidity value.

Application

The Microduino Temperature and Humidity sensor can be used in a range of applications including HVAC systems, dehumidifiers, home automation, data recording or in a weather station.
