The conditions in a fish tank are being controlled using sensors and a microprocessor. To keepthe fish healthy, the temperature must be at 25°C and the oxygen content needs to be 20 ppm(parts per million). The tank contains a heater and an oxygen inlet controlled by a valve.microprocessorsensor A sensor Bheater oxygen supply (a) Name the two sensors used in this application .Sensor ASensor B [2] (b) Describe how the sensors and the microprocessor are used to maintain the correctconditions in the fish tank.
