Product Overview
The AGS2620 is a high-sensitivity, low-power Total Volatile Organic Compound (TVOC) sensor based on MEMS technology. It utilizes a high-performance semiconductor silicon-based resistive sensing chip with specialized digital module acquisition and gas sensing technology to ensure high reliability and excellent long-term stability. Its features include low power consumption, rapid response, strong anti-interference capabilities, and a long service life. The sensor is pre-calibrated and tested for large-scale applications, making it suitable for monitoring various TVOC gases such as ethanol, ammonia, sulfides, benzene vapors, smoke, and other harmful gases. It finds broad application in air purifiers, home appliances, and fresh air systems.
