Soldered 108994 MH-Z19 CO2 Air Quality Sensor

Soldered 108994 MH-Z19 CO₂ Air Quality Sensor features the non-dispersed infrared principle to detect CO₂ in the air. This sensor includes a built-in temperature compensation and is highly sensitive to gas detection. The 108994 CO₂ sensor provides extremely accurate readings, and its outputs are on UART and Pulse Width Modulation (PWM). This sensor operates at a 3.6V to 5.5V voltage range and a 0°C to 50°C working temperature range. This sensor consumes less electricity and provides a long service life.
