The 7Semi ENS160 Air Quality Sensor I2C Probe (ES-12183) is a compact and ready-to-use air quality sensing module built to measure indoor environmental conditions. It uses the advanced ENS160 multi-gas sensor to detect volatile organic compounds (VOCs) and other indoor pollutants, helping you understand the quality of the air around you. The probe provides clean, processed digital outputs that make monitoring easy.
This sensor communicates over a standard I2C interface and works at 3.3 V, making it simple to connect to popular controllers like Arduino, ESP32, or Raspberry Pi. With features like long-term stability, low power use, and reliable performance across a range of temperatures and humidity levels, it’s a great choice for smart home systems, air purifiers, HVAC monitoring, and other environmental projects.
