MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -The most common environmental sensors are pressure and gas sensors. For the first sensor type the stimulus is given by a defined applied gas pressure level, and for the second sensor type by a certain chemical concentration of the gas species to be investigated.

Detailed explanation-2: -Environmental sensors include: soil sensors, temperature and humidity sensors, gas sensors, rainfall sensors, light sensors, wind speed and direction sensors, etc. Not only can environmental information be accurately measured, but the data can also be tested, recorded and stored.

Detailed explanation-3: -A sensor is a device that detects and responds to some type of input from the physical environment. The input can be light, heat, motion, moisture, pressure or any number of other environmental phenomena.

Detailed explanation-4: -Temperature sensors. Humidity sensors. Airflow sensors. Pressure sensors. Vibration sensors. Water leak detection sensors. Contact closure sensors.
