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 ...
