2nd Board: The terrarium had a humidifier system inside. It was made with a Capacitive Soil Moisture Sensor connected to an Arduino Nano and a connective board. | 2nd Board: | ||

When the soil got drier (over value 400 read by that sensor, whose values are approximately this: wet is < 400, dry is > 400), a 5V Relay Module also connected to the board, activated a 5V Humidifier made with a piezoelectric. When the soil got humid again (under value 400) the humidifier stopped until the soil got dry again. The relay and humidifier received an extra supply of energy from an MB-102 3.3V/5V Power Module plugged into electricity. | When the soil got drier (over value 400 read by that sensor, whose values are approximately this: wet is < 400, dry is > 400), a 5V Relay Module also connected to the board, activated a 5V Humidifier made with a piezoelectric.
