Why create it and how it works
Laws regarding stubble burning takes into account the current season, wind speed, relative humidity, temperature and other factors. When a farmer, a peasant or anyone who lives in the country wants to get rid of weeds, controlling all these parameters is very difficult. Thus, a device is created that takes into account these three parameters and, depending on the observation, informs with a simple light-code if burning is allowed, banned or allowed under supervision and caution. Its operation is based on the Hall effect. This physical principle allows knowing the wind speed using a magnetic sensor that detects each turn of the anemometer. In addition, a temperature and humidity sensor reports the other variables, so that the integrated circuit evaluates the situation.
Stubble burning is a very common and dangerous practice, responsible for many fires on our planet. But why extinguish fires when we can prevent them?
