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(); ...
