Wave TVOC Environmental Gas Sensor – UART

The Wave TVOC Environmental Gas Sensor – UART is a compact, high-performance module designed for accurate detection of Total Volatile Organic Compounds (TVOCs) in the air. It uses a semiconductor-based sensing principle, where gas molecules react with heated sensitive materials to alter resistance, allowing precise measurement of VOC concentrations. With fast response times, stable operation, and a simple UART communication interface, this sensor offers reliable performance in smart home systems, air purifiers, and industrial air quality monitoring.



Engineered for scalability and long-term use, the sensor features high sensitivity, low power consumption, and a service life of up to 5 years. It’s ideal for applications such as environmental monitoring, vehicle air purification, or handheld air quality analyzers. The module supports 5V power input and 3.3V logic level UART output, making it easily integrable with microcontrollers like Arduino, Raspberry Pi, and ESP32.
