Feb 9, 2025 · Infrared sensor MH-Z19B is a universally applicable, small sensor that enables the use of non-dispersive infrared (NDIR) for detection of the carbon dioxide in the air with good selectivity. This sensor is easy to use and has a built-in temperature sensor that can do temperature compensation.

Mar 10, 2018 · Tutorial on IR Proximity sensor interface with arduino, to detect obstacles, with code and circuit diagram.

Feb 20, 2020 · Hi, I am having an issue with Serial Monitor not showing the correct readings in serial monitor. I have 2 MH sensor which is detecting the rpm/revolutions for my DC motor using encoder disks. When i tested the sensors individually, it shows correct analog and digital reading as picture shown.

An Arduino library for the MH-Z19X CO2 sensor, which unlocks commands while supporting both software/hardware serial. Recovery for Dysfunctional Sensors: See examples for the recovery code.

Jul 28, 2022 · New Commands & Examples for the MHZ19 with Arduino, supporting hardware & software serial.

This is an easy to use sensor module you can use to sense the intensity of infrared light reflection on surface. You can use this as the line tracking sensor to make line following robots, or proximity sensor to sense object or obstacle in front of the optical sensor pair.

This repository contains an Arduino implementation for MH-Z CO2 sensors, including MH-Z14A, MH-Z19B, and MH-Z19C. It aims to consolidate information on these sensors in one place for easy access. The sensor is available for ~20 bucks at the usual places.
