MH-Z19B Infrared CO2 Sensor Module for CO2 monitor
The MH-Z19B Infrared CO2 Sensor Module is an advanced device designed for accurate monitoring of carbon dioxide (CO2) levels in various applications. Here’s a description of the sensor module:
The MH-Z19B utilizes infrared absorption technology to measure CO2 concentrations in the surrounding environment. It features a compact and integrated design, making it suitable for integration into CO2 monitoring systems, environmental monitoring equipment, indoor air quality monitors, HVAC systems, and other applications where precise CO2 level measurement is critical.
This sensor module offers a wide measurement range of 400-5000 parts per million (ppm) for CO2 concentration, allowing it to detect even trace amounts of CO2. With its high accuracy of ±50 ppm + 3% of the measured value, the MH-Z19B provides reliable and consistent readings, ensuring precise monitoring of indoor air quality and environmental conditions.
Equipped with a digital output signal, typically using UART (Universal Asynchronous Receiver-Transmitter) communication protocol, the MH-Z19B seamlessly integrates with microcontrollers and other digital devices, enabling real-time data acquisition and analysis.
The sensor module features a fast response time of approximately 60 seconds, allowing for rapid detection of changes in CO2 concentration. Additionally, it has a short warm-up time of around 3 minutes, ensuring quick readiness for accurate CO2 measurement after power-up.
With its low power consumption and wide operating temperature range of 0°C to 50°C, the MH-Z19B is suitable for both indoor and outdoor applications. It also offers a broad storage temperature range of -20°C to 60°C, ensuring reliable performance even in harsh environmental conditions.
Periodic calibration may be required to maintain optimal accuracy, and calibration procedures can typically be performed using calibration software provided by the manufacturer.
Overall, the MH-Z19B Infrared CO2 Sensor Module provides a reliable, accurate, and easy-to-use solution for monitoring CO2 levels in various settings, contributing to improved indoor air quality, environmental monitoring, and energy efficiency.
