A smart terrarium that is self-sustained by using various sensors such as LDR sensor, Temperature sensor, humidity sensor, Soil moisture sensor, ultrasonic sensor as well as an Arduino MKR1000 WIFI and a 20x4 LCD screen. The referred parameters are such as the Temperature of the closed system, the Humidity level inside the terrarium, Light intensity inside, the level of Soil Moisture. Temperature: Fan is turned on automatically by the system when temperature exceeds the threshold. The fan is automatically turned off when the temperature comes under the normal set value. Humidity: A misting system is automatically turned on given the humidity inside the terrarium falls below the threshold and when it exceeds the correct set value, it is switched off by the system. Light Intensity: Measured in units of LUX and when the light intensity drops below the threshold level, polychromatic LEDs are turned on to mimic sunlight. Soil Moisture: A self-watering drip-irrigation system wherein when the moisture level in the soil falls below the threshold, it is automatically pumped into the soil by the system.
