The sensor module has four pins, two of which are for VCC and Gnd and the other two can simultaneously output analog and digital data. As you can see in the image above the module has two onboard LEDs ...

Rajguru Electronics has released the ADIY pH sensor module, a sensor for measuring the potential of hydrogen (pH) in any liquid. The low-cost sensor can precisely measure the hydrogen-ion activity in ...

Why ? Because I need it working on my reef-pi setup and reef-pi contributors does not provide driver code for writing a custom ph module reader. First of all need to calibrate PH-4502C board, put the ...

The CJMCU-103 rotary angle sensor/rotation sensor module is good for detecting an absolute rotation position. The sensor itself is a dust-protected continuous rotation SMD potentiometer so we can turn ...

The 8-channel line tracking sensor module is specially designed for the line patrol function of robot car. It integrates 8PCS high-sensitivity infrared sensors, which can quickly and accurately detect ...

This work presents a low-noise and high linearity potentiostat design used for biomedical implantable rumen pH sensor applications by using current mirror combined with chopper technique. The ...

Abstract: In this paper, an adjustable angle sensor based on rotary potentiometer for measuring and monitoring finger flexion is proposed. Most of the current system is unadjustable, inaccurate, ...

The sensor in question produces a relatively tiny voltage of -0.414 to +0.414 volts, and requires a very high input impedance.
