ECO SMART PLANT CODE

arduino

this is the code for that the soil moisture sensor knows when wettingthe plant (the percentage of humidity change according to the plant) and whit the 5v pump itwets it when the humidity is lower than the threshold. whit a ldr it measures the brightness, so when you turn on the lamp i front of the ldr, the stepper motor is actived and make the tend go up, when the lamp is turned off, the opposite effect occurs. there is also a temperature sensor, that measures the temperature. all values above results are shown on an lcd screen, the values have been mapped so that they are in percentage.
