Creating alerts to water your plant

Before creating all the exciting wireless gardening projects you'll find in this chapter, we are going to start with one important thing: testing whether the sensor is working properly!

For that, here is the sketch to check that the sensor is functioning correctly:

// Library
#include <SHT1x.h>

// Pins
#define dataPin  4
#define clockPin 5

// Create instance for the sensor
SHT1xsht1x(dataPin, clockPin);

void setup()
{
Serial.begin(115200); // Open serial connection to report values to host
Serial.println("Starting up");
}

void loop()
{
  // Variables
float temp_c;
float temp_f;
float humidity;

  // Read values from the sensor
temp_c = sht1x.readTemperatureC();
temp_f = sht1x.readTemperatureF();
humidity = sht1x.readHumidity();

  // Print the values to the serial port
Serial.print("Temperature: ");
Serial.print(temp_c, DEC);
Serial.print("C / ");
Serial.print(temp_f, DEC);
Serial.print("F. Humidity: ");
Serial.print(humidity);
Serial.println(...
