ENS160 Air Quality Sensor I2C Probe

The 7Semi ENS160 Air Quality Sensor I2C Probe is a compact digital air-quality sensing solution designed for monitoring indoor air quality, VOC levels, eCO2, and air-quality index (AQI). Built around the ScioSense ENS160 multi-gas Metal Oxide (MOX) sensor, it provides processed digital air-quality data for HVAC systems, smart buildings, indoor environmental monitoring, IoT devices, and automation applications.

The probe provides TVOC output from 0 to 65,000 ppb, eCO2 output from 400 to 65,000 ppm CO2-equivalent, and AQI-UBA values from 1 to 5. Its digital I²C interface enables straightforward integration with microcontrollers, data loggers, and embedded monitoring systems.

The sensing assembly is enclosed in a ventilated plastic probe housing, allowing ambient air to reach the sensing element while providing mechanical protection against direct contact with the internal sensing assembly. A 4-wire cable provides 3.3 V, GND, SDA, and SCL connections for convenient remote installation.
