I have a task where i need to data log and control a pump based off a ph sensor and a dissolved oxygen sensor readings. When levels are too high the pump turns on. When levels are (good) pump turns off. I would also like (but not necessary) to monitor this on a screen .
I've read your job description and I can help you with this project because I have 4+ years of experience using RPi latform for customized IOT applications.
I've worked with DO2 and PH sensors for a farm control application last month using RPi, so I can do it for you. Please let me of further details and task deadline. Thanks.

Hello, First, We need to select the best sensors. Then according to sensor communication type we can read the data. Then we use a phase controller to control the system. We also need the write driver to turn the pump on and off. send me more detail if you want.
