A 3 in 1 robot on wheels performs three tasks in the agricultural field such that harvester, seed sowing mechanism, and irrigation through a robotic arm. The robot is controlled over the internet with live streaming and control streaming. Robot's advantage over driving combining vehicle that robot has lightweight as it excludes driver seat so less fuel consumption is there. Multiple functionalities reduce to purchase separate machines for separate tasks.

Using a mobile application (Android App) controlling and monitoring the electrical appliances in a room:
-Securing the entrance in the room using RFID
-Creating a fire alarm system that turns off all the appliances when the fire is detected
-Water Tank filling automation mechanism
-Monitoring the room temperature and lights when detects the presence of a person in the room using an ultrasonic sensor
-Monitoring roomtemperature and cooling system

In the agriculture field, the excessive or less amount of water for the crops is harmful so the amount of water should be in a controlled way. For yielding the best quality crops, a fixed amount of water supply is needed. Sometimes due to extreme rain also destroys many crops so there should be a minimum amount of water supply before the rain. The water pump should be controlled by a smart IoT device in real-time for the accurate supply of water to the crops depending upon environmental factors and soil moisture threshold.

Unique Features:-
1. Controlling through WLAN (UDP protocol) as well as though the internet (Google Firebase)
2. EEPROM Configuration:- End User will connect the device to pc through USB cable and WiFi SSID, passwords, firebase host, firebase auth key and soil moisture threshold will be stored in EEPROM, This how an end-user can self-set up the device.
3. An SD adapter is embedded with Atmega328p for data logging of the environmental factors, Water pump status with the date and time stamp fetched from RTC will be stored in .CSV in an SD Card for data analytics.

Using a mobile application (Android App) and system application (Java Swing App) controlling and monitoring the electrical appliances in a room. Securing the entrance in the room using RFID and monitoring the room temperature and lights when detects the presence of a person in the room using an ultrasonic sensor, temperature, and other sensors.
