# A minimial arduino library fro SHTC3 Temperature & Humidity sensor

A bare minimal arudino lib for this sensor for low power applications based on official [SHT libraries](https://github.com/Sensirion/arduino-sht).

If you find this library usefull and want to support open software consider to **donate**.



  



## Usage

 The library is designed for low power applications that will poll the reading periodically. When the sensor is not reading

 it is keep asleep consuming less than 1 uA.

```c++

 

    SHTC3 sensor(Wire);

    void setup() {

            Serial.begin(9600)

            Wire.begin();

            sensor.begin();

    }

    void loop() {

            s.sample();

            Serial.print(F("[SHTC3] T:"));

            Serial.print(s.readTempC());

            Serial.print(F(" Cº  /   H: "));

            Serial.print(s.readHumidity());

            Serial.println(F(" %"));

            delay(2000);

    }

```

## Technical notes

- The sensor is ___NOT__ 5V tolerant: If using 5V boards a 3.3V power source or 3.3V regulator need to be used. Most arduino boards have 3.3V power line that can be used to power the device. SCL & SDA require also logic level shifters are required as this pins are nor 5V tolerant.

- Pull-up resistors are typically needed on SCL & SDA lines. Resistor values will depend on frequency and bus configuration.

- Sensor supports up to 400kHz (fast I2C).

## Compilation options:

 if __ARDUINO_SHTC3_NOFLOAT__ is defined no float computation is done. Temperature and Humidity will return a 16bit integer. This optimization will reduce the code size more at expense of precision in the reading.

 

## Notes:

Library has been tested on a arduino pro mini 3.3V.
