ABSTRACT This final project discussed abaout the design of an automatic temperature controller broiler for chicken broiler farm based an arduino uno as controller, LM35 as temperature sensor,light as heater and electric fan as cooler. The temperature required for broiler chicken is between 30ᵒC - 33ᵒC. if the temperature is above 33ᵒC then the electric fan will be active, if the temperat…
