Soil moisture sensor with arduino

See how it was to use the Arduino connected to a soil moisture sensor to control the lighting of an LED, which could also be a relay for activating a solenoid valve for automated irrigation.
The soil moisture sensor module has 4 pins, which must be connected respectively to: an analog port, a digital port, ground and 5 volts. The analog output is used to see how measurements vary. The digital output will deliver a high or low signal to the arduino, which can be regulated in the module using a phillips screwdriver or screwdriver.

Ele pode oxidar e como evitar isto

[@openmaker]

Se oxidar, é fácil trocar o sensor.

[@genildops7ga]

@@openmaker sei que facio, mais deveria ter um solução pra Isto pois em pouco tempo teria que trocar vários por mês

[@openmaker]

@@genildops7ga , acho que ele deve durar cerca de um ano, não é tão frágil assim.

@@openmaker valeu e muito obrigado pela atenção
