arduino-sht
Unofficial repository for Sensirion Humidity and temperature sensor support on Arduino
Supported sensors:
- SHTC1
- SHT3x-DIS (I2C)
- SHT3x-ARP (ratiometric analog voltage output)
Installation
Download arduino-sht either via git or from the releases page and place it in the Arduino/libraries directory. After restarting the Arduino IDE, you will get menu items under libraries and examples.
Integrating it into your sketch (Example for SHTC1)
Assuming you installed the library as described above, the following steps are necessary:
- Import the Wire library like this: From the menu bar, select Sketch > Import Library > Wire
- Import the arduino-sht library like this: From the menu bar, select Sketch > Import Library > arduino-sht
- Create an instance of the
SHTC1
class - In
setup()
, make sure to init the Wire library withWire.init()
- If you want to use the serial console, remember to initialize the Serial library with
Serial.begin(9600)
- Call
shtc1.readSample()
in theloop()
function, which reads a temperature & humidity sample from the sensor - Use
shtc1.getHumidity()
andshtc1.getTemperature()
to get the values form the last sample
Important: getHumidity()
and getTemperature()
do not read a new sample from the sensor, but return the values read last. To read a new sample, make sure to call readSample()
Sample code
#include <Wire.h>
#include <shtc1.h>
SHTC1 shtc1;
void setup() {
// put your setup code here, to run once:
Wire.begin();
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
shtc1.readSample();
Serial.print("SHTC1:\n");
Serial.print(" RH: ");
Serial.print(shtc1.getHumidity(), 2);
Serial.print("\n");
Serial.print(" T: ");
Serial.print(shtc1.getTemperature(), 2);
Serial.print("\n");
delay(1000);
}
