Keep the probe area free from air bubbles and direct ambient light for consistent readings. No pull-up resistor is required.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, the module outputs 0–4.5V analog signal that can be read directly by Arduino analog pins. Use the 5V supply from the board.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow do I calibrate the sensor?\u003c\/summary\u003e\u003cp\u003ePlace the probe in clean water for a baseline (0 NTU) and note the voltage. Use a solution of known turbidity to establish the scaling factor in your code.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eCan the probe be fully submerged?\u003c\/summary\u003e\u003cp\u003eThe sensor probe is waterproof and designed for immersion, but the signal module and connections must remain dry.
