A digital humidity sensor is an electronic device that measures the humidity in its environment and converts its findings into a corresponding electrical signal. As shown in the circuit diagram, humidity sensors can be divided into two groups: as each category uses a different method to calculate humidity: relative humidity sensors and absolute humidity sensors. The digital humidity diagram shows that the sensors vary widely in size and functionality. A digital humidity sensor diagram can be created using EdrawMax or EdrawMax Online and shared across the hardware development team, who will make the product as per the design. These digital humidity sensors are commonly used in the meteorology, medical, automobile, HVAC, and manufacturing industries.
