A pH meter measures the hydrogen-ion activity in water-based solutions, indicating its acidity or basicity expressed as pH. (Wikipedia: pH Meter). pH level is an important indicator in many scenarios, especially in monitoring soil conditions and water quality. A pH sensor is widely used in farming, gardening, hydroponics, aquaponics, swimming pools and spas, sewage treatment, education, environmental monitoring, and many other applications.

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. |
