DS18B20 is a single-bus digital temperature sensor with features of ultra-small size, wide range of applicable voltage and measurable temperature and high resolution.
This sensor has a piezoelectric transducer that responds to voltage changes, generating a measurable change in output voltage that is proportional to the force of vibration . In this way, it is possible to know the vibration force , as opposed to the digital vibration sensor that only counts time.
Electronic Brick - Soil moisture sensor is mainly used to detect soil moisture content . The module can obtain the soil moisture value or limit through analog or digital pins.
