MH-Z19B NDIR CO2 sensor for indoor air quality monitoring
RWF 62,000
The MH-Z19B NDIR CO2 Sensor is an advanced sensor designed for monitoring indoor air quality by measuring carbon dioxide (CO2) concentrations. Using Non-Dispersive Infrared (NDIR) technology, it provides precise, reliable measurements of CO2 levels in real-time. The sensor is ideal for applications in air quality monitoring, HVAC systems, and smart home environments. It has a fast response time, low power consumption, and can communicate through UART or PWM interfaces, making it easy to integrate into various devices and systems. The MH-Z19B is an essential tool for ensuring healthy indoor air quality and promoting well-being in residential and commercial spaces.
