PH4502C PH Value Detection Water/Liquid Sensor Module without Electrode Probe

The pH of the solution (pH) is an important property of the solution. Industrial grade PH transmitters are expensive; the PH test pens on the market are mature products that cannot be used for secondary design development; P composite electrodes output mV-level voltage signals and the microcontroller cannot directly identify and process them. Based on these conditions we have designed this. PH sensor module. This sensor is low in price easy to use high in measurement accuracy and can directly output 0~5V or 0~3V analog voltage signals.

Parameter:

1>.Working voltage: 5V

2>.Measuring range: 0-14PH
3>.Measuring temperature: 0-60℃
4>.Accuracy: ±0.01PH (25℃)
5>.Response time: less than 1minute
