Gas Sensor MQ-131 Ozone Module sen0138-r and extended data loggingDetect Gas Changes with a Practical Air Sensor The Gas Sensor MQ 131 Ozone Module is a gas sensor designed for air quality projects, leak alerts, and ventilation monitoring. It is a practical fit for makers, students, and engineers who want reliable sensor data in embedded builds. Key details include Interface: UART. Important: Most gas and chemical sensors work best after warm up and calibration. Readings can drift with temperature, humidity, and
