Connecting pressure sensor to Arduino to collect pressure and time data

I'm trying to build a pressure data logger using an Arduino and Mindman MP47P-03-F1 (https://www.mindman.com.tw/proimages/pdf/E_MP47_S.pdf) pressure sensor, the sensor is connected to an outer 12-24 VDC power source. I've connected the analog wire…

Is there a manometer available to use with Arduino?

I used an analog manometer in a plumb system. I would like to actually track information about water pressure across an entire building on different points and record all this information to analyze changes on pressure. I was wondering if there is a…

5V Pressure sensor module with 3.3V ADC

I'm using ESP32 to read analogue pressure readings from this pressure transducer. My Problem is this sensor outputs 0.5V – 4.5V linear voltage output based on the pressure but ESP32 can only handle 0 - 3.3V in the ADC inputs. Can anyone advice me to…

Reading pressure sensor using Arduino analog

I'm using a Arduino Uno to read pressure and I want to know if I have wired/coded the sensor correctly. I'm not sure I'm getting the correct readings (it could be the right readings - I just want to check I have done everything right). The sensor I…

Force Sensitive Resistor OverLoad

I've got just a simple question. What happens when I overload Force Sensitive Resistor (FSR). Example Here. Let's say that it's got force sensitive range between 100g and 10 000g. What would happen if I'd create pressure about 100kg? I see that…

Control Air Pump Depending on Pressure Sensor

I am working with an Arduino Mega, a 12V micro air pump, and a MP3V5050 air pressure sensor. The sensor outputs an analog voltage depending on the pressure reading in an inflatable member. I'd like to turn on the micro air pump when the pressure is…

Analog Read gives Erratic behaviour in Struct

I'm getting some very strange behaviour from a Haptic feedback system I'm trying to make. The test code works fine as a Multiple-In One-Out in the main loop, but once I moved the code to the Struct, I ended up with very erratic behaviour on the…

Pressure Sensor-MPX10DP with amplifier and Arduino UNO - output to kPa

I'm working with an Arduino UNO. I'm trying to use this Sensor to obtain the pressure in kPa. I'm using a tl084cn to amplifier the signal. But I don't know what values I'm getting and what to do with them. Not applying pressure prints 0, if I apply…

CRC test fail on MS5803-14BA pressure sensor - what can I do?

Problem: I bought two MS5803-14BA sensors and I soldered them myself to a SOIC-8 PCB to be able to use them. Only one sensor is used in my circuit. To access it, I use an Arduino Pro Mini 8MHz/3.3V with a library that has a CRC check for the sensor.…
