Works well but probe is short

The sensor functionality is good, but the probe cable is a bit shorter than I expected for deep tank applications. I had to extend the wires myself. Otherwise, the detection accuracy is decent for non-industrial use.

Reliable readings after warm-up

I noticed the readings drift slightly during the first minute of operation. After letting it warm up for 60 seconds, the data becomes very consistent. Make sure to seal the connections if using it in a permanently wet environment.

Great educational tool

Bought this for a high school environmental science project. Students were able to measure sediment levels in local creek samples easily. The module is robust enough to handle student handling, and the documentation is clear.

Easy integration with ESP32

Connected this directly to an ESP32 without any level shifters. The voltage levels match perfectly. The sample program included in the package saved me hours of writing driver code. Very satisfied with this purchase.

Good value, needs careful calibration

The build quality is solid for the price. It took a bit of trial and error to get the baseline reading correct in clear water, but once calibrated, it detects changes in turbidity accurately. The digital pin is a nice bonus for simple threshold alerts.

Perfect for my hydroponics setup

This sensor works exactly as described. I integrated it into my automated plant watering system to monitor water clarity. The analog output is stable, and the included code made calibration very easy. Highly recommended for DIY projects.

5 FAQ

Q: Does the package include the connecting cables?

A: Yes, the module typically comes with a 3-pin connector cable. Please check your specific shipment contents, as bulk orders may vary slightly.

Q: Is this sensor waterproof or just the probe?

A: The probe head is designed for immersion in liquid, but the main PCB board is not waterproof. You should house the board in a protective enclosure if there is a risk of splashing.

Q: Can I use this to measure saltwater turbidity?

A: Yes, it can detect turbidity in saltwater. However, please rinse the probe with fresh water after each use to prevent corrosion on the metal contacts over time.

Q: What is the maximum current consumption?

A: The module consumes approximately 20mA to 30mA when the IR LED is active. Ensure your microcontroller pin can supply sufficient current or power it externally.

Q: How do I calibrate the sensor for clear water?

A: Place the probe in a container of distilled water. Adjust the potentiometer on the board or modify the offset value in the provided code until the analog reading matches your defined 'clear' baseline (often near 5V or 1023 on 10-bit ADC).
