As the name suggests, the SENSOR ARRAY is an array of sensors. We have the DHT11 which has both Thermometer and Relative Humidity sensors which are read through a single data line. A Mic with a basic LM386 Amplifier Circuit which can be read by the MOTHERBOARDS Analog pins. A Light Dependent Resistor which is also read by an Analog pin. And to record all the data that these sensors pick up, a Micro SD Card slot. You can upload the data to a spreadsheet and make graphs to help understand things like the brightest time of the day, or the hottest, loudest, most humid etc.
