Liquid PH0-14 Value Detection Sensor Module + PH Electrode Probe BNC for Arduino AVR STM32 PH Sensor Module ph Tester

Notes:1. Its output signal cannot be measured with a voltmeter, it needs a controller such as Arduino to receive the signal2. Refer to the user manual and test code: Liquid PH0-14 Value Detection Sensor Module + PH Electrode Probe BNC for Arduino AVR STM32 PH sensor module ph tester Descriptions: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: 5V2>.Measuring range: 0-14PH3>.Measuring temperature: 0-60℃4>.Accuracy: 0.01PH (25℃)5>.Response time: less than 1minute6>.PH sensor interface: BNC interface7>.Temperature sensor interface: XH2.54-3PPin definition:1>.VCC:Supply voltage positive, 5V2>.GND:Supply voltage negative3>.GND:Analog signal output negative4>.PO:Analog signal output positive.Output range is 0V-5V.5>.2V5:Reference voltage 2.5V output6>.T1:Temperature sensor DS18B20 signal output port
