Procedure

DHT 11(Temperature and Humidity) Sensor

The humidity sensing component of the DHT11 is a moisture holding substrate with the electrodes applied to the surface. … The DHT11 converts the resistance measurement to relative humidity on a chip mounted to the back of the unit and transmits the humidity and temperature readings directly to the Raspberry Pi.

Rain Drop Sensor

The rain sensor works on the principle of total internal reflection. … An infrared light beams at a 45-degree angle on a clear area of the windshield from the sensor inside the car. When it rains, the wet glass causes the light to scatter and lesser amount of light gets reflected back to the sensor.
