Interface Turbidity Sensor with Arduino / ESP | DIY Turbidity meter | Techeoics 

you are right, yes it works with 5V but is not accurate, and i think as i kept on using 5v all the time i might have destroyed by esp board. When i connected a new one and used 3v as supply, it even detected minor changes in turbidity that it was not happening before, although the range is less but it's fine. thanks!

Hey buddy I am having an issues could you plz give me your social media account

There are three exposed pads close to the output pin (middle pad). You need to solder a jumper across two of them. Refer to the 1-minute and 22-second mark in this video to view the soldered pins. This resolved the ramdon values issue. Good luck.

Here are some steps you can take to troubleshoot and address the issue: 1. Calibration: Ensure that the turbidity sensor is properly calibrated. Follow the manufacturer's guidelines or user manual for calibration instructions. Calibration helps the sensor provide accurate readings. 2. Clean the Sensor: Check if there is any debris or contamination on the sensor. Clean it gently using a soft brush or a lint-free cloth. Even in clear water, small particles might be present that can affect readings. 3. Check for Air Bubbles: Ensure there are no air bubbles trapped on or around the sensor. Bubbles can interfere with the sensor's ability to accurately measure turbidity. 4. Verify Sensor Placement: Confirm that the sensor is correctly positioned in the water. Ensure it is submerged adequately and not near any disturbances or sources of turbulence that could affect readings. 5. Power Supply Stability: Turbidity sensors can be sensitive to fluctuations in power supply. Make sure the power source is stable and not experiencing voltage variations. 6. Environmental Factors: Consider environmental conditions such as temperature, which can impact sensor performance. Ensure the sensor is within the specified temperature range for accurate readings. 7. Sensor Health: Check for any signs of damage or wear on the sensor. If the sensor is damaged, it may not provide reliable readings. 8. Interference from Other Sensors or Equipment: Ensure there is no interference from other sensors or electronic equipment that could be affecting the turbidity sensor. Techeonics www.techeonics.com

in essence the sensor is giving an analog value from 0-5V, which the Arduino translates as 0-1023. the example I gave translates the Arduino value of 0-1023 to voltage but you can do what ever you want with it. void loop() { // read the input on analog pin 0: int sensorValue = analogRead(A0); // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V): float voltage = sensorValue * (5.0 / 1023.0); // print out the value you read: Serial.println(voltage); }

Try another sensor

So, got another sensor. Same thing, keeps giving out the same value

I did notice your module had green and Red LEDs on the side. Mine has but doesn't come on

​@@cauesomenzido you mean I should connect vcc and ground pin with one jumper wire

@@technicalsai1400 no, you need to solder a jumper between the pads exposed. Not to ground or vcc

@@cauesomenziI tried and soldered the two pads but still it is showing it’s dirty in the lcd

I could use someone’s help

Drop as a mail with the problem and error code and screen shot . Will help you out thetecheonics@gmail.com.

I think sir sensor is not working

@@Wake-up-toreality how did you check if the sensor isn't working? did you check if the sensor changes voltage according to the water quality?
