Alcohol Sensor Solution for Disinfection Robots

Disinfection robots are increasingly used in public health, medical, and industrial environments. Compared to manual disinfection, robots can operate in unattended or low-personnel areas, reducing direct exposure to viruses and disinfectants, making them a key part of standardized disinfection systems.

Among various disinfection methods, alcohol disinfection is widely used in robot systems due to its maturity and efficiency. However, alcohol also requires careful safety control.

How Disinfection Robots Perform Alcohol Disinfection

Robots generate alcohol vapor in an internal disinfection module and use a pneumatic diffusion system to release it evenly into target spaces. Following preset paths, robots ensure thorough diffusion, effectively eliminating airborne viruses, bacteria, and microorganisms. This method is more suitable for large or complex spaces than static spraying.

Properties of Alcohol (Ethanol) as a Disinfectant

• Flammable and volatile

• Vapor is irritating

• Can form explosive mixtures with air

Alcohol disinfection must maintain a controlled concentration: too low reduces effectiveness, too high creates fire and explosion hazards.

Alcohol Concentration Control: Key to Safe Operation

• Program Control: Adjust theoretical concentration via spray volume, duration, and path

• Real-time Monitoring: Alcohol sensor feedback on ethanol concentration in the air

Program control alone cannot handle ventilation changes, space differences, or device aging. Real-time monitoring is essential.

Why Alcohol Sensors are Essential

• Dynamically assess current disinfection status

• Prevent alcohol concentrations from exceeding safety limits

• Provide reliable data for system control strategies

• Support disinfection data logging and traceability

Sensors upgrade robots from simple execution devices to intelligent systems with perception and feedback capabilities.

Practical Challenges in Sensor Selection

• Raw sensor outputs are complex and hard to integrate directly

• Developing amplification circuits and algorithms in-house is time-consuming and risky

• Limited space in robots requires compact, low-power sensors

A smart alcohol sensor with pre-processed outputs and calibration is ideal for integration.
