A Review of Smart Greenhouse Farming by Using Sensor Network Technology

Abstract

This paper mainly discusses the smart greenhouse farming at low cost. This farming is based on wireless multi-sensor network technology using ZigBee. It helps in the growth of plants in any climate by providing plant-friendly environmental conditions. A greenhouse environment measurement in GSM-SMS was known in this paper. GSM-SMS is a technique that gives a notification to our mobile through sensors. This GSM-SMS system includes mobile dialogue and microcontroller. The greenhouse environment is a thing that plants grow at a certain place under highly protected conditions such as a glass-covered area. The greenhouse environment is a special application of wireless sensor networks, wireless sensor network control is the key point. By monitoring and controlling the greenhouse environment, we can see many major improvements, such as it provides good quality of crops. The key factors for the good quality and productivity of crop growth in the greenhouse are monitoring and controlling them. Plant growth is facilitated by maintaining humidity, temperature, CO2 concentration, and light intensity. This event could be happened easily by using a multi-sensor technique. The temperature sensor, humidity sensors are present to control and monitor. This will lead by giving more outcomes and fewer costs when comparing it with regular farming techniques. Here we use LoRa technology which means LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology.
