Overview: ENS161
Digital Metal-Oxide Multi-Gas Sensor
with permanent and low power operating modes
ENS161 datasheet
Version 1.1 Release Date: 2024-11-29 Document Status: Production CONTENTS PAGE The ENS161 is a multi-gas sensor, based on metal oxide (MOX) technology with four sensor elements supporting isothermal and low-power operating modes plus an unrivaled wealth of fully processed output signals.
The independent hotplate control allows the detection of a wide range of volatile organic pounds (VOCs) including ethanol, toluene, hydrogen and oxidizing gases with superior sensitivity. The ENS161 supports intelligent algorithms to process raw sensor measurements on-chip. These algorithms calculate TVOC- and CO2-equivalents, various air quality indices (AQIs) and perform humidity and temperature pensation, as well as baseline management, all on chip.
Raw sensor measurements can be read for further customization. The LGA-packaged device includes SPI and I²C slave interfaces to municate with a main host processor.
The ENS161 is a proven and maintenance-free technology, designed for high volume and reliability.
