Usually with an ADC of some type, but this can vary with the type of sensor. Most modern microcontrollers contain at least one built in ADC usually with a multiplexer allowing measurement of multiple sensors.
Hygrometer is another name for a moisture sensor.
A heart beat counter circuit typically consists of a heart rate sensor connected to a microcontroller (such as Arduino) which processes the sensor data and displays the heart rate on a digital display (such as an LCD screen). The heart rate sensor measures the electrical activity of the heart and converts it into a signal that the microcontroller can interpret. The microcontroller then calculates the heart rate based on the sensor data and displays it on the screen.
A moisture sensor typically measures the electrical resistance between two electrodes. When the sensor comes into contact with moisture, the resistance decreases due to the conductive properties of water. This change in resistance is then converted into a moisture level reading that can be interpreted by a controller or display.
That depends on the specific microcontroller.
A moisture sensor is a device that measures the amount of moisture in a substance or environment. It is commonly used in agriculture to monitor soil moisture levels for optimal plant growth, and in household appliances like humidity sensors in air conditioners and clothes dryers.
Same as a switch
A humidity sensor switch works by detecting the amount of moisture in the air and then activating or deactivating a device, such as a humidifier or dehumidifier, to regulate the level of moisture. When the sensor detects that the humidity is too high or too low, it triggers the device to turn on or off, helping to maintain the desired level of moisture in the air.

The PIC is a specific architecture of microcontroller.
The voltage of the 8031 microcontroller is 2.7V to 5.5V.
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
