【正文】 r a timely control instructions can give, control water pump, heater equipment, Which adjust the aquatic animals box to maintain environmental parameters for achieveing the purpose of fish survival environment steady. The whole system design is divided into two parts that is hardwareand software . Hardware circuit has six modules. they are main control chip module design, system power supply module design, water temperature detection/water level measurement modules, buttons and LCD module, relay control motor module, buzz alarm module. The software is modular design. The independent modules are divided into four big C language program. They are main program, 1602 LCD processing procedures, delay the calling program, temperature sensor DS18B20 program. Through the operation during missioning, it shows that this design aquatic animals box control system has operation simple, reliable operation, hardware design flexibility, low cost characteristic.
