JOY-IT SEN-CCS811V1 Air Quality Sensor – VOC & eCO2 Monitoring Module

The JOY-IT SEN-CCS811V1 is a compact and precise air quality sensor module based on the CCS811 gas sensor chip. It measures volatile organic compounds (VOCs) and calculates an equivalent carbon dioxide level (eCO2), making it suitable for environmental monitoring, smart home projects, and embedded systems.

Key Features

• VOC & eCO2 Monitoring: Detects a wide range of volatile organic compounds (TVOC) and estimates CO2 equivalent values for indoor air quality assessment.



• Digital I²C Interface: Easy integration with microcontrollers such as Arduino and Raspberry Pi via I²C communication.



• Wide Operating Voltage: Works with 3 V to 5 V power supply — compatible with most development boards.



• Multiple Measurement Modes: Includes idle (low power) and several active modes with different measurement intervals for power vs responsiveness optimization.



• Compact & Lightweight: Small module (21 × 18 × 3 mm) for easy placement in projects and prototypes.

Technical Specifications

Setup & Operating Notes

For accurate measurements, a “burn-in” period of about 48 hours is recommended after first use, and a 20-minute warm-up time is suggested when starting from idle or switching modes. The sensor supports different timing modes that balance responsiveness and power consumption depending on your application. ([turn0search19](#))

Applications

This sensor module is ideal for environmental monitoring systems, air quality stations, smart home controllers, HVAC system interfaces and IoT air quality projects. Use it to track VOCs and approximate CO2 levels in spaces like homes, offices or classrooms.
