## Overview

The Teyleten Robot pH Sensor Module delivers precise acidity and alkalinity detection across the full pH 0-14 range, with a rapid ≤5 second response time and robust operation from 0-80°C. Designed for Arduino integration, it features low power consumption (<0.5W), analog voltage output, and a compact surface-mount form factor, making it ideal for industrial and electronic monitoring applications.

## Description

Features: Heating voltage: 5 plusmn 0.2V (AC middot DC) Working current: 5-10mA Detectable concentration range: PH0-14 Detection Temperature range: 0-80 ℃ Response time: le5S Settling Time: le60S Component Power: le0.5W Working temperature: -10 ~ 50 ℃ (nominal temperature 20 ℃) Humidity: 95% RH (nominal humidity 65% RH) Module Size: 42mm times 32mm times 20mm Output: analog voltage signal output With 4pcs M3 Mounting Holes

Review: Decent for the $$ - Got it setup and reading data using a few tutorials. Needed to have a software calibration value before tuning more finely with the potentiometer. Ph Model seems tight. I can get it to be accurate on the high end or on the low end but not both. If I dial in the high PH then the low gets inaccurate. I will order this product again because I only need it accurate on the high side. don't need the full range of measurement. (could also be my calibration mixes) Doesn't come with calibration fluid. I will probably make a video of this on my YouTube channel 'Random Projects with Sam'

Worked as expected

### ⭐ Unstable readings, difficult to use.
*by M***E on February 14, 2023*

Very difficult to calibrate even with a known good pH meter the readings are all over the place. The op amp circuit is poorly designed and one can’t adjust the offset voltage below 2.66 on my unit. Will never work at 3.3 and barely works at 5 volts. Single ended approach does not work well when a pH probe outputs a differential voltage above and below a pH value of 7 at approximately +/- 59mV/ per 1 pH increment and this probe is good to 0.5 pH step according to data sheet so 29.5mV per .5 pH increments. Do not buy this unless your willing to spend a lot of time on the bench and fine tuning the math in your code. I recommend using a voltage divider on the output of your using 3.3 volt and especially for ESP32 where the ADC only accept up-to 1.0-1.2 Volts max full scale resolution otherwise you’ll never get it working. Good luck and buyer beware.. Mike S.
