ENS160+AHT21 Carbon Dioxide CO2 eCO2 TVOC Air Quality Temperature Humidity Sensor Module: Digital multi-gas sensor for indoor air quality monitoring
For the DIY enthusiast or smart home builder focused on creating a healthier living space, this sensor module is your tool for monitoring indoor air quality. While many sensors just detect gases, this one helps you understand your home's environment, giving you control over air purification and automation systems.
The ENS160+AHT21 module detects a wide range of gases and VOCs like toluene and NO2, with outputs for TVOC and eCO2. It integrates pre-calibrated algorithms, so you get accurate readings without complex software setup. Use it with Arduino for projects that alert you to air changes before they become noticeable, ensuring your family breathes easier.
With I2C and SPI interfaces, it connects easily to your systems, and its resistance to humidity makes it reliable in various conditions. This module replaces models like CCS811, offering enhanced detection for home automation, air purifiers, or consumer appliances.
