The MH-Z19 is a sensor that uses the non-dispersed infrared principle to detect CO2 in the air. It has built-in temperature compensation and high sensitivity to gas detection, and therefore has extremely accurate readings, and its outputs are on UART and PWM. It consumes little electricity and has a long service life. * Model: MH-Z19 * Voltage: 3.6V - 5.5V * Response time: less than 60s * Working temp.: 0°C - 50°C * Size: 33 x 20 x 9 mm / 1.3" x 0.8" x 0.4" https://elecena.pl/product/25316622/co2-sensor-mh-z19 2024-02-16 https://elecena.pl/product/25316622/co2-sensor-mh-z19 2024-02-22 https://elecena.pl/product/25316622/co2-sensor-mh-z19 2024-02-26
