ADVANCE ROTTEN ONION DETECTION SYSTEM BY USING GAS AND TEMPERATURE SENSOR

Onion production in India has wide impact on financial set-up and financial status of growers/consumers [1]. India ranks second in onion production within the world.Under ambient conditions the onions are stored at a temperature of 31-36 OC with ratio i.e. RH of 66-71%[3]. Which means temperature and humidity are two major parameters that ought to be controlled within desire range. But because of continue change in Indian climate onions can rot [6]. Once the method of rotting starts, it grows rapidly and causes huge amount of loss. Onion is extremely important vegetable crop not just for internal consumption but also as highest exchange earner among the fruits and vegetables. So it’s essential to stop onion losses like weight loss, rooting, sprouting, decay and rotting . Hence,So , authors have studied different conventional storage techniques and different losses through online survey, visual observations and through field visits and intended to introduce a system to manage onion losses. During this system authors have used basic sensing elements (sensors), controlling components (Microcontroller) with online feedback and parameter controlling agents to manage this parameter with an extra addition of onion shade covered by shade-net. During this system, major gases like ammonia , carbon dioxide , temperature & humidity emitted by onions [6] are detected and used for temperature control.
