Arduino Water Conductivity Meter

This project will demonstrate how to build a water level monitor using an arduino nano a solu sl067 water level sensor and an indicator.

Arduino water conductivity meter.

Understanding this data will help you understand how different events in and around your. So in order to fix this issue we need to include the temperature coefficient in the code. With this product main control board such as arduino and the software library you can quickly build an electrical conductivity meter plug and play no welding. Aqueous conductivity is commonly expressed in millisiemens cm ms cm and natural waters range from 0 05 1 5 ms cm for freshwater lakes streams up to about 55ms cm for sea water.

The focus is to introduce students to the fabrication of the probe and expose. How to make a benchtop ph meter with an arduino uno and the gravity analog ph sensor from atlas. You have to sequence the probes. If there is an increase or decrease in temperature the reading will be false as conductivity changes as per temperature.

Water up to 3 ms cm can be consumed though most drinking tap water is below 0 8 ms cm. Ec off and ph on ph off and ec on. Arduino water pollution monitor. This is a feature inherent to measuring conductivity and is unavoidable.

Advanced microprocessor conductivity instruments can vary the voltage applied to the sensor which enables them to extend the range of a potentiometric probe even further. Arduino electrical conductivity ec ppm tds. Student groups construct simple conductivity probes and then integrate them into two different circuits to test the probe behavior in solutions of varying co. Temperature compensated tds sensor with arduino.

The above two codes are valid only if the temperature of the water is 25 degrees celcius. This project will allow you to create your own conductivity sensor and use an arduino to gather data about the pollution levels of your community water sources. Student groups construct simple conductivity probes and then integrate them into two different circuits to test the probe behavior in solutions of varying conductivity salt water sugar water distilled water tap water. Project tutorial by newmc.

While measuring conductivity the ec meter emits electric pulses that travel through the water and cause the ph electrode in the same tank to produce garbage readings that oscillate wildly.
