Overview

The 101020067 is a Grove-compatible evaluation board featuring the MH-Z16 NDIR infrared CO2 sensor. It provides a stable carbon dioxide measurement solution with high sensitivity and low power consumption for air quality monitoring. The module supports multiple output interfaces including UART, PWM, and analog voltage for flexible integration into embedded systems.

Why Choose This Part

The module utilizes Non-Dispersive Infrared (NDIR) technology, providing high selectivity and oxygen independence. It operates on a 4.5V to 5.5V supply and features built-in temperature compensation for stable readings between 0 and 50 degrees Celsius.

Applications

Indoor Air Quality Monitoring
Integration into HVAC systems or smart home monitors to detect CO2 levels for ventilation control.
Greenhouse Climate Control
Monitoring carbon dioxide concentrations to optimize plant growth in agricultural environments.
Industrial Gas Leak Detection
Use in safety systems where CO2 monitoring is required for personnel safety in confined spaces.
