Easily add gas sensing to your IoT application with the DGS4 89x-Series I2C Gas Sensor: small, low-profile, factory calibrated sensors with an I2C interface for easy integration into wireless, portable, and other IoT sensor solutions.
100% factory calibrated gas concentration with EEPROM-stored calibration coefficients. High performance electrochemical gas sensors with integrated temperature and relative humidity sensors. Low-profile mezzanine connector. Accurate, linear, and fast response. Multiplex 89x-Series sensors for a custom array. Open-source firmware for rapid development. Long life (10+ years). RoHS & REACH compliant.
Available in two package sizes: the 891-Series (13 x 19 mm) is ideal for space-constrained applications like wearables and indoor IoT devices; the 895-Series (18 x 24 mm) is ideal for industrial and outdoor air quality applications.
