Unitronic presented for the first time at the trade show SENSOR +TEST 2015 in Nuremberg, a low-power USM-MEMS-VOC sensor module that enables an especially rapid detection of different volatile organic compounds (VOCs) in the air. The Unitronic Sensor Module (USM) has small dimensions of only 15 × 17 × 3 mm. It is equipped with a high-precision, long-term stable TGS 8100 miniature Micro-Electro-Mechanical Systems (MEMS) sensor from Figaro and reacts within less than 8 seconds to the release of harmful gases. The current consumption in continuous operation is less than 14 mA.
The USM-MEMS-VOC is designed for a supply voltage of 1.8V. As a result of its low current consumption and small size, the sensor module is especially suited for use in battery-operated applications. A PWM signal for analog interpretation, three digital outputs, a UART interface, automatic base-level adjustment and automatic humidity/temperature compensation by means of an optional external sensor makes it easy to integrate the USM-MEMS-VOC into a wide range of applications.
