The Engineering Behind Automatic Sanitizer Dispenser Control Board

This dedicated control board forms the intelligent core of automated sanitizer dispensing systems, expertly integrating an infrared (IR) proximity sensor for touchless activation and a robust relay for precise pump control. Its architecture is optimized for real-time response, detecting hand presence and initiating the dispensing cycle with minimal latency. The design prioritizes operational reliability and ease of integration into various enclosure designs.

Constructed with industrial-grade components and a durable PCB, this module ensures long-term stability and resistance to typical environmental factors in high-traffic areas. Its robust build quality makes it suitable for both DIY projects and semi-industrial deployment, offering consistent performance without compromise.

Integrated Infrared Proximity Sensing

The primary technical feature is its highly responsive infrared proximity sensor, providing accurate, non-contact hand detection. This integration eliminates the need for external sensing modules, simplifying system design and reducing component count. The sensor’s rapid detection capabilities ensure instantaneous activation of the dispensing mechanism upon hand presentation, enhancing user experience and hygiene.

High-Current Relay Output

A crucial secondary feature is the onboard high-current relay, designed to directly control various types of dispenser pumps, including peristaltic, diaphragm, or solenoid valves. This robust switching capability resolves common operational pain points by safely isolating the low-voltage control circuitry from the higher power requirements of pump motors, ensuring reliable and long-lasting performance for the actuator without requiring an external driver board.

What power supply voltage is recommended for this control board?

The control board typically operates within a 5V to 12V DC range, making it compatible with common power adapters and battery configurations. Always check the specific board’s silk screen for exact voltage input.

Can this board control different types of pumps?

Yes, the onboard relay is designed to switch various types of DC or AC pumps, including peristaltic, diaphragm, and solenoid valves, provided their current and voltage ratings do not exceed the relay’s specifications (e.g., 10A @ 30VDC / 250VAC).

Is the infrared sensor’s detection range adjustable?

Many versions of this board offer a potentiometer to fine-tune the IR sensor’s detection range, allowing customization from typically 2cm to 10cm to suit different dispenser designs and activation distances.

Does this control board provide feedback or a control signal for external microcontrollers?

This particular board is designed as a standalone control unit, primarily focusing on direct actuation. It generally does not offer advanced data feedback or dedicated communication lines for external microcontrollers beyond its operational state.

How should I connect the pump to the relay output?

Connect the pump’s power line through the normally open (NO) and common (COM) terminals of the relay. Ensure the pump’s power supply is appropriate for the pump itself and the relay’s maximum switching capabilities.
