🌱Universal Protocol: MODBUS-RTU RS485 and 0~2V Analog Voltage

🌱Wide-range Power Supply: Can be powered with supply voltage within 3.6V ~ 30V

🌱Strong Robustness: Suitable to be immersed in soil or water for a long time, anti-corrosion

🌱Maintainance-Free: A unique junction efficiently improves the problem of junction clogging

Description

This pH Sensor with a waterproof aviation connector measures the hydrogen-ion activity in water-based solutions, indicating its acidity or basicity expressed as pH. pH level is an important indicator in many scenarios, especially in monitoring soil conditions and water quality.

This pH Sensor is designed with industry standards. It adopts international advanced solid dielectric and large-area polytetrafluoroethylene liquid junction, which is not easy to block and convenient for maintenance. Its electrode is IP68, the transmitter is IP65 rated, waterproof in a tight seal, and capable of withstanding long-term constant use in professional scenarios. This pH Sensor comes with a MODBUS-RTU RS485 serial communications protocol and 0~2V Analog Voltage output. It can be easily connected and integrated with other devices such as data loggers, Converter, displays, etc. This cost-effective pH sensor features low-power consumption, compact size, portability, and high integration.

Seeed also provides the SenseCAP Portal and SenseCAP Mate to help users better manage and check data remotely.

Note

If you find white solid granular crystals around the probe shroud, this is a normal situation and please do not worry. It is caused by temperature change, environmental change, or redox during the process of delivery. However, it will not affect the nature of the internal solution and the normal operation of the sensor.

If you find it, please use a wet paper towel to gently wipe off the crystals on it, please do not let it near your children to avoid accidental ingestion.

FAQ

Q: Is it factory calibrated? How to calibrate?

A:

Yes, the device is fully calibrated prior to shipment from the factory.

About calibration, please refer to the document:

https://raw.githubusercontent.com/Jenkinlu001/SenseCAP/master/PH10-AppNote-PH%20Calibration%20by%20Modbus%20Command.doc

Q: Why is the temperature output from the sensor inaccurate?

A: PH electrode itself has no temperature sensor, the temperature is the plate temperature sensor; If necessary, you can access the NTC (10K, 3950) thermistor temperature sensor.

Q: Can the sensor be used in soil? How to install?

A:

Yes, Yes, the principle is still to measure the pH in the soil moisture, so it will be affected by the soil moisture, and the drier the soil, the greater the error.

Installation method: Dig out a pit, fill the pit with some water, stir the soil into a slurry, and then place the sensor glass probe. Be careful not to overexert yourself and avoid hard objects such as stones, otherwise the probe will be damaged.
