IoT Ready
Exactly what I needed for my remote monitoring station. The UART interface saves GPIO pins on my microcontroller.

Good Accuracy
The sensor reads consistently after calibration. It took some time to get the calibration right, but once done, it holds well.

Great for Aquaponics
Works perfectly with my ESP32 setup. The serial output is stable and easy to parse. I use it for monitoring my fish tank water quality.

Cable Length Issue
Works well technically, but the cable is a bit short for my deep container setup. Had to use an extension.
Q: How often do I need to calibrate?
A: We recommend calibration every 2 weeks for continuous monitoring, or before each critical measurement session.
Q: Does it come with calibration powder?
A: No, calibration solutions are sold separately. We recommend using standard pH 4.01 and 6.86 buffer solutions.
Q: Can I use this with Raspberry Pi?
A: Yes, you can connect it via a USB to TTL serial adapter. Ensure voltage levels are compatible.
Q: Is the module itself waterproof?
A: The module electronics are not waterproof. Only the probe head is designed for submersion. Please keep the circuit board dry.
Q: Is the Arduino library open source?
A: Yes, the library is open source and available on our GitHub page for easy integration into your projects.
