How to operate soil moisture sensor with Arduino

The soil moisture sensor is the most amazing sensor used to measure the quantity of water present in the soil and defines the moisture level of the soil as the output. Because of its amazing operating principle this sensor used in application such as automatic irrigation system, agriculture research applications, landscape irrigation, indoor planting system, and lawns. I have also made an advance level project  "Smart Plant Watering System" using a soil moisture sensor.

Buzzer with Arduino

A buzzer or piezo speaker is an audio signaling device commonly used to produce sound. Piezo buzzer produces sound based on the reverse principle of the piezoelectric effect. The buzzer is a less costly and light weighted electronic device that’s why it is used in computer, alarm device, refrigerator, microwave oven, security devices and so on. 

Bluetooth module with Arduino

HC-05 Bluetooth module is used for wireless communication. It is designed to replace the wired connection. It requires a wireless serial connection setup to communicate with devices.  HC-05 Bluetooth module can be operated in master or slave configuration.   It uses serial port UART to communicate with devices. It can communicate with devices maximum range up to 10 meters with data transfer rate up to 1 Mbps. Because of its amazing features, it used in multiple applications such as home automation, wireless robot, industrial control units, wireless mouse, GPS receivers, etc.
