Raspberry Pi Water Ph Sensor

In this tutorial i ll be using the atlas scientific ph sensor it s an industrial grade sensor that works well with the raspberry pi it s fully submersible up to the bnc connector in both fresh and saltwater.

Raspberry pi water ph sensor. With some python you can monitor the ph of a pool aquarium or any water body. The ds18b20 and ds18s20 represents a very simple sensor.

Raspberry pi based water quality measurement system uses a ph sensor for obtaining the water quality parameters.

When water is detected the raspberry pi emails out an alert to a recipient group and calls a phone number list via voip playing a stored wave file with a spoken alert phrase. How to connect a ph sensor to a raspberry pi in this tutorial i will show you how to connect a ph sensor to a raspberry pi.

An advantage is that many different 1 wire components can be connected in series and read out by a single gpio. It is possible to find environmental sensors at a low cost which can be connected to low cost microprocessors like raspberry pi. The water level sensor s s pin is connected to ch0 adc channel 0. An optional bi color led connected in series with 330 ω resistors to gpio 14 and 15 provides feedback.

These raspberry pi sensors are addressed via the so called 1 wire bus. The plus and minus pins go to 3 3 v and ground respectively. However these modules can not measure additional information such as humidity and or air pressure. Raspberry pi has the capacity to monitor with readings ov over the past few years environmental technology has improved and become very accessible to the final consumers.
