A factory that manufactures cleaning products has a system that monitors conditions throughout the manufacturing process. The inputs to the system are: | Input | Binary value | Condition | | :--- | :--- | :--- | | A | 1 | $\mathrm{pH}>7$ | | | 0 | $\mathrm{pH} = 35 °C | | P | 1 | Pressure > = 80 \% | | | 0 | Pressure = 80 \% and the temperature > = 35 °C or - The temperature 7 Draw a logic circuit to represent the alarm system in the factory. Each logic gate must have a maximum of two inputs. ![](https://files.sudostudy.com/76781ffd32ff3ec8b58192e71b3be9e0d14752dbf17248878f8cd4cc7bc264ce.jpg?height=913&width=1637&top_left_y=1589&top_left_x=223) (b)Complete the truth table for the given logic problem. | A | T | P | Working space | X | | :--- | :--- | :--- | :--- | :--- | | 0 | 0 | 0 | | | | 0 | 0 | 1 | | | | 0 | 1 | 0 | | | | 0 | 1 | 1 | | | | 1 | 0 | 0 | | | | 1 | 0 | 1 | | | | 1 | 1 | 0 | | | | 1 | 1 | 1 | | | [4] (c) A sensor and a microprocessor are used to monitor the pH of the cleaning products. The system records each reading that is taken. If the reading is greater than 7 a warning message is displayed on a monitor. Explain how the sensor and microprocessor are used in the system. \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ \_\_\_\_ [6]
