The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

Heat detectors are the best ones for detecting flame fires. Unlike other types of fire detectors, heat detectors can be used in polluted and aggressive environments. They are resistant to various ...
