Claim 1:
2. The Internet of Things (IoT) based hydroponic farm system of claim 1, further comprising:
a fluid transfer system connected to the plurality of hydroponic plant growing zones within a hydroponic farm, wherein the fluid transfer system is configured to carry nutrient solution from a nutrient reservoir to the hydroponic plant growing zones;
wherein each of the plurality of hydroponic plant growing zones includes:
a first plurality of sensors including at least a nutrient temperature sensor, an ultrasonic level sensor configured to measure a nutrient level in the hydroponic plant growing zone, and an atmospheric temperature and humidity sensor, wherein each of the first plurality of sensors is configured to generate first sensor signals and publish the first sensor signals to the zone controller connected to the first plurality of sensors through the data distribution service middleware; and
a first plurality of actuators including a ventilation fan configured to generate air flow in the hydroponic plant growing zone and at least one submersible pump configured to pump the nutrient solution through the fluid transfer system, wherein each of the first plurality of actuators is configured to receive actuation instructions from the zone controller as subscribers of the data distribution service middleware.
