Sensor Amplifier Board/Module for Testing PH Value (pH0-14) (OT3470)

sensor module for measuring the pH values of liquids with a microcontroller. This module amplifies the values measured by a pH sensor (such as the OT3489 Electronic Probe - order separately). This makes it possible to read them out with a microcontroller such as an Arduino or an esp32.Working temperature: -10 ~ 50 (nominal temperature 20)Working humidity: 95% RH (nominal humidity 65% RH)Size: 42 mm × 32 mm × 20 mmHeating voltage: 5 ± 0.2V (AC DC)Working current: 5-10mARange: PH0-14Response time: 5SStabling time: 60SElement power: 0.5W TO – Temperature OutDO – Digital Out Trigger (3.3V)PO – 0-5V Analog Out for PHGND – GroundVCC – 5VDC Input PowerDimensions: 42mm × 32mm × 20mmProvides a 0-5V analog output – perfect for Arduino but also ESP32.Great module for Biorobotics or other projects. For example, make your own IOT/Smart Home Water PH meter in combination with a wifi module. This way you can remotely measure the water quality in a swimming pool, rain barrel, water tank, pond or aquarium.
