Decent sensor
It works, but the documentation could be better. Had to search online for code examples. Sensor itself seems durable though.

Great for Hydroponics
Works perfectly with my Arduino setup. I use it to monitor nutrient levels in my hydroponic garden. The analog output is stable and easy to read.

Excellent Value
Best price I found for a TDS module with this build quality. Using it for a water quality logging project and it has been reliable for months.

STM32 Compatible
Connected easily to my STM32 board. The voltage levels match well with the ADC. Good build quality on the probe itself.

Good but needs calibration
Accurate after calibration with a standard solution. Out of the box readings were slightly off, but once tuned it works well for general monitoring.
Q: Can I use this to test drinking water safety?
A: This sensor measures Total Dissolved Solids only. It does not detect bacteria or viruses. Use it for general quality monitoring, not safety certification.
Q: What calibration solution do you recommend?
A: We recommend using a standard 1413 ppm TDS calibration solution for best accuracy during the initial setup process.
Q: Is the electronic module waterproof?
A: Only the probe head is waterproof (IP67). The circuit board module should be kept dry or housed in a waterproof enclosure.
Q: Does it require specific libraries?
A: No specific library is needed. It outputs an analog voltage that can be read using standard analogRead functions on most microcontrollers.
Q: What is the maximum water temperature?
A: The recommended maximum water temperature is 50°C. Exceeding this may damage the probe or affect reading accuracy.
