can this device be used in flowing water?

also i have trouble calibrating it. when put in the KCl Solution it shows 4.5 PH and it doesnt really change when turning the potentiometer.

Hello, we mainly have 4 models of pH sensors that don't make sense.
The SEN0161 as well as the SEN0161-V2 use laboratory grade probes. They are not suitable for long time measurements, but are more accurate.
SEN0169 and SEN0169-V2 use industrial grade probes and support 7*24 measurement.

Regarding the above products, the sensors with V2 suffix support 3.3V-5V specification microcontrollers (e.g. ESP32, etc.). Sensors without the V2 suffix only support 5V power supply with controllers, and we recommend that you use them with Arduino UNO/MEGA/Leonardo controllers.
Meanwhile, we only provide pH4.0, pH7.0 calibration solution for SEN0161-V2.

If you order more than one product in one order, you just need to pay the shipping fee once.

Finally, how long would it take for my order to arrive in Peru, Lima?

Can python code for pH sensor v2 be implemented on ph sensor v1 also?

Hello, whats the Analog output Voltage of this Module? I have it connected to a ADS1115 to measure the pH Voltage with a Raspberry Pi, but i can measure only Garbage with it... in the puffer solution of pH 7 it returns 2 Volts and at pH 4 it return 1.25. So it would be around 3.5 Volts at pH 14? Would be great to know whats the range of the output voltage is. greets

Hi, Analog voltage output range =0~ input voltage value 5V; If you are using a motherboard analog value other than 1024, you will need to change it in your code.

Hi. I would just like to ask. Regarding this code in the sample:
pHValue = 3.5*voltage+Offset;
Where does the 3.5 come from?

Why the module show me low indicator LED? I use 5V of Arduino Uno

Hi,

Did you follow the calibration process properly?
Please make sure to calibrate properly before using it. You can find the calibration steps in the WIKI.

Hello everyone. I have bought this sensor, along with the DFR0300, but when I put the two sensors together in the same solution, the value on the pH sensor increases. Anyone know how I can fix this?

Hi, can you tell me, what's the meaning of equation for converting mV to PH, why we are multiplying by 3,5?

I have the same situation.

I use ads1115 to convert i2c to analog pin.
on ads 1115 has a 16-bit resolution, do I need to change the existing formula in the library because of that resolution?

thank you for the response

I am doing a project that consists of detecting the PH, turbidity and chlorine levels of the water with arduino. I will connect the arduino to an ESP8266 to make it work with IoT. I've already solved the PH and turbidity sensors, but haven't found a sensor for chlorine. Do you know of any chlorine sensor or other way to get the chlorine level?

HI! im making a project for a water testing center and i've wonder if you got any suggestion on a chlorine sensor for water working with arduino

hi
Can you let us know mv output reference range for the board... we are testing this with a gateway..... the readings we are getting in mv are strange......
