Cubic Sensor Gasboard-7500HA Ultrasonic Oxygen Sensor Module (0-100% O₂, 0-10L/min) - UART TTL & Analog Output
The Cubic Sensor Gasboard-7500HA is a high-precision ultrasonic oxygen and flow sensor module, compatible with 3.3V logic systems like Arduino, Raspberry Pi, and ESP32. It provides continuous, maintenance-free monitoring of oxygen concentration (0-100%) and flow rate (0-10 L/min) via UART TTL and analog voltage outputs.
Features
- Ultrasonic Time-of-Flight (TOF) principle for drift-free, calibration-free operation.
- Dual measurement of oxygen concentration (0-100%) and flow rate (0-10 L/min).
- Fast 100ms response time with UART TTL (3.3V) and analog voltage outputs.
- Wide operating voltage range (DC 4.75–12.6V) with full-scale temperature compensation.
- Compact, lightweight design for integration into medical and industrial flow systems.

The Gasboard-7500HA utilizes advanced ultrasonic Time-of-Flight (TOF) technology to measure the speed of sound within a gas stream, which varies with oxygen concentration and flow velocity. This non-dispersive, physical sensing principle ensures long-term stability and eliminates the need for consumable electrochemical cells or routine calibration, providing a maintenance-free solution.
The module features integrated signal conditioning and temperature compensation, delivering a stable analog voltage output (200mV–2500mV) for both parameters alongside a digital UART TTL interface for direct microcontroller communication. Its robust design supports continuous operation in environments from 5°C to 50°C, making it suitable for embedded systems requiring reliable gas monitoring.
