JWGas-VOC(Z16) TVOC eCO2 Air Quality Sensor is a compact indoor air quality monitoring sensor designed for HVAC systems, building automation, air purifiers, demand-controlled ventilation, and laboratory environmental monitoring. Based on MOX gas sensing technology and an integrated ENS161 gas sensor, it measures equivalent TVOC, equivalent CO2, AQI-U, AQI-S, temperature, humidity, and dew point.
With optional RS485 Modbus RTU or SDI-12 V1.3 digital output, low power operation modes, temperature and humidity compensation, and wall-mounted installation, this sensor is ideal for IoT-based indoor air quality monitoring and smart building integration.
2. Product Overview
JWGas-VOC(Z16) TVOC eCO2 Air Quality Sensor is designed for continuous indoor air quality monitoring and digital environmental data acquisition. It can detect a wide range of volatile organic compounds, including ethanol, toluene, hydrogen, and oxidizing gases, and uses intelligent algorithms to calculate eTVOC, eCO2, and multiple air quality index outputs.
The sensor is suitable for smart buildings, HVAC systems, indoor air quality monitoring, demand-controlled ventilation, air purification equipment, home appliances, and laboratory applications. Its RS485 Modbus RTU and SDI-12 output options make it easy to integrate with data loggers, IoT gateways, building automation systems, and cloud monitoring platforms.
According to the supplier manual, the sensor supports SDI-12 V1.3 or RS485 Modbus RTU, 5–28 V DC power input, IP50 protection, wall-mounted installation, default 2 m cable length, and a compact sensor body size of 111 × 25.5 mm.
