In this work we presente the results obtained with a electronic circuit to control temperature, water, humidity and fertilizer of plants in a greenhouse. Different sensors were located in the greenhouse and electrovalves were activated by different circuits. Fans and heaters were located to introduce fresh air or to heat depending of the temperature. A computer program was developed to control by a microprocessor the different parameters. Parametrs were introduced by a keyword, a LCD display helps to vizualise the actual parameters status.One purpose was to make operation very friendly to by manipulated for people with no knowledge in electronic. Two solar cells were used to charge a automotor acumulator which supply the electrical energy to the system. The greenhous is autonomous from the point of view of elestrica energy, so it can be placed in remote towns. For the moment was built a pilot greenhouse (2x2x1.5 mts.)by in the future it will be posible to build it bigger.
