Solar Grass Cutter with Water Spraying Vehicle

The paper aims at designing and fabricating a solar grass cutter with water spraying system using RF Technology to reduce man power, pollution and usage of electricity in gardening. Both the grass cutting and the water spraying application can be executed in parallel. Power supply performs an amazing function anywhere people lives and works. The residing values and affluence of a country range at once with the growth with the usage of power. Worlds electricity requirement is growing at an alarming price because of commercial growth, improved and huge use of electrical gadgets. The high-quality alternative opportunity supply is from the sun energy. In this design the source energy is ambitious from the sun radiation by using PV panels and it is stored in 12V rechargeable DC battery. The proposed proto-vehicle performs two operations that are controlled using a switch. The first operation is grass cutting, the grass cutting blade is connected a DC Motor. The second operation is the spreading of water/pesticide, here we use a water pump connected to the spreading nozzle by the means of hoses. The battery is connected to the RF Module with controls all the motors. The RF session encompasses an RF transmission and reception. This Tx/Rx pair (RF module) functions at a frequency of 434 MHz. The data required for the RF transmitter is received from series of serial data and is transmitted in wireless manner using the RF antenna. The data that is transmitted is received by RF receiver in the RF module with same operating frequency of transmitter. The RF module has a pair of encoder/decoder and is used with the module itself. The encoder encodes the parallel data for the transmission system and the at the reception decoder unit is used for decoding the data. Input signals are transmitted through four channels and the outputs are observed with a set of four LED’s with respect to corresponding switches.
