This is a MH-Z19B CO2 sensor library for Arduino. It has been built from scratch to support hardware and software serial with a small footprint. The MH-Z19B is a NDIR (Non-Dispersive Infrared) type ...

This CO2 sensor meter will be used to detect the actual CO2 measurements in parts per million. For this project we wanted to create something that would be used in a lab. So we wanted to create an ...

Its MH-Z14A NDIR CO2 sensor and GP2Y1010AU0F optical dust detector are read by a WiFi-enabled microcontroller, this time the Arduino Nano RP2040 Connect, which ultimately reports its findings to ...

A gas sensor is a device that detects the presence of gases in a specific area. This research work demonstrates the effectiveness of gas sensors based on graphene oxide (GO) and copper oxide (CuO) ...

Mainly temperature / humidity sensors, but also one water leagage sensor. Because I wanted to follow also CO2 level in some rooms, I decided to make my own CO2 sensor device using STM32WB and zigbee.

The main objective of this research is to detect the forest fire by sensing temperature and atmospheric carbon dioxide (CO2) levels to prevent the forest fire and to provide exact information using ...
