The Arduino Solution

We built a low-cost, Arduino-based system that:

• Monitors air pressure in the pump tubing

• Detects when air pressure falls below a defined threshold

• Calculates the corresponding pressure in kilopascals

• Makes a HTTPS request to a Google Apps Script web app URL when the pressure drops below 1.0 kPa. 

• Uses Google’s MailApp service to automatically send an email alert to a designated address, notifying the receiver that the pump may no longer be functioning.

• Includes a backup battery to ensure that the system will still operate if power fails. 

​

How it Works

Our system consists of a:

• MPX5010DP Pressure Sensor

• Arduino Nano 33 IoT Microcontroller

• INIU Portable Charger, Slimmest 10000mAh 5V/3A Power Bank 

• The MPX5010DP pressure sensor is wired to the Arduino Nano 33 IoT Microcontroller which draws power from the INIU Portable Charger, Slimmest 10000mAh 5V/3A Power Bank that is plugged into the wall (120v).

• When the MPX5010DP reads a pressure below a given threshold, it will notify the arduino, which is programmed to alert responsible personnel.

• The INIU Portable Charger acts as a backup power source so that if the pump fails due to a power outage the system will still send an alert.
