yes, we use ESP32 S2 MINI inside. we use the hall effect water flow sensor to measure the water flow. It is magnetic. please check more details here. www.aliexpress.com/item/1005006630839984.html, please buy here, it is 3D print housing, we don't have much in stock, we are still working on the mass production. thanks.
mmmmmmm.....in your note...I see frequency....I guess the output is not a continuous voltage but a square pulse...at a higher flow rate the faster the pulses...so...at 1 L/min...you will have 11 pulses...
Good!!!... Hence this flow sensor can be connected to an arduino..given the fact that the output signal from the sensor is a 0.5 to 4.5 volts? ?? I guess that the flow rate should be linear with the output voltage...right? ....can you answer those questions? Thanks.
Thanks for sharing the video Manasmicro is one of the best Electromagnetic flow meter manufacturer in pune India. We supply best electromagnetic water flow meter at best price www.manasmicro.com/electromagnetic-flow-meter/
Hello , question , can I put an alarm on when the flow is under a certain flow level ? If I have a pump that gives normaly 150l\ minute , the flow will be measuret with a zj lcd m , and the pump wil get blocked by something so the flow become 90 l \ minute ....can I get an alarm at that moment ?
