Dual Mini Diaphragm Water Pump System with Rocker Switch Control
This circuit consists of two Mini Diaphragm Water Pumps connected in parallel to a 12v 7ah Battery through a Rocker Switch. The switch controls the power supply to both pumps, allowing them to be turned on or off simultaneously. The circuit is designed to pump water from a tank through nozzles when activated.

This circuit is designed to automatically control a mini diaphragm water pump using an IR sensor. When the IR sensor detects the presence of an object, it activates the pump via a TIP120 transistor and a 12V relay. The system is powered by separate 12V and 5V batteries for the pump and sensor, respectively.

This circuit is designed to control a Mini Diaphragm Water Pump using an ESP32 microcontroller, which interfaces with multiple sensors and a relay module. The ESP32 reads inputs from IR sensors and HC-SR04 ultrasonic sensors to determine when to activate the relay, which in turn powers the water pump. The power supply provides the necessary voltage for the pump and the relay, while the ESP32 and sensors are powered by the ESP32's 3.3V output.

Usage Instructions
Integration into a Circuit
- Power Supply: Connect the positive voltage supply to Pin 1 and the ground to Pin 2. Ensure that the voltage supply is within the operating range of the pump.
- Activation: The pump operates when the power is applied and stops when the power is cut off. Use a relay or a transistor switch to control the power to the pump from a microcontroller like an Arduino UNO.
- Tubing: Attach flexible tubing to the inlet and outlet ports of the pump. Ensure a secure fit to prevent leaks.
Best Practices
- Avoid running the pump dry, as this can shorten its lifespan.
- Use a filter at the inlet to prevent debris from damaging the diaphragm.
- Ensure the voltage supply is stable to prevent damage to the pump.
- Mount the pump securely to minimize vibrations and noise.
Example Arduino UNO Code
// Define the pin connected to the relay or transistor
const int pumpPin = 7;
void setup() {
// Set the pump pin as an output
pinMode(pumpPin, OUTPUT);
}
void loop() {
// Turn on the pump for 5 seconds
digitalWrite(pumpPin, HIGH);
delay(5000);
// Turn off the pump for 10 seconds
digitalWrite(pumpPin, LOW);
delay(10000);
}
Troubleshooting and FAQs
Common Issues
- Pump not operating: Check the power supply and connections. Ensure the voltage is within the specified range.
- Low flow rate: Verify that there are no blockages in the tubing and that the inlet filter is clean.
- Excessive noise: Ensure the pump is securely mounted and that the tubing is not kinked.
FAQs
Q: Can the pump operate continuously? A: Yes, but it is recommended to allow periodic rest to extend the pump's life.
Q: Is it safe for pumping drinking water? A: Check with the manufacturer's material specifications to ensure compatibility with potable water.
Q: Can the pump handle hot liquids? A: The pump is rated for temperatures up to 60°C. Do not exceed this limit.
Q: How do I control the flow rate? A: The flow rate can be controlled by adjusting the input voltage or using a flow control valve on the outlet tubing.
