摘要：The paper presents a low cost, organic, microcontroller driven control system which maintains relative humidity level of a chamber as per the level set by the user along with maintainace of ambient temperature. It can be viewed as an integrated agricultural solution which takes care of the crop yield and post harvested storage by regulating the temperature and humidity factors which are most critical. Unlike other techniques, this approach uses the energy liberated by the stored products in store houses, green-houses to drive humidifiers and dehumidifiers. Along with use of biodegradable materials as the humidity controlling agents, this system presents a robust electronic design for humidity sensor (H20-G) to interact with the microcontroller and an intelligent electronic valve assembly to regulate the flow of air as per the need. A noble algorithm is developed for getting error-free reading from the sensor and comparing it with the user defined value with the help of ADC and microcontroller. In depth analysis in terms of energy requirements and availability is done and the results obtained confirmed that humidity and temperature can be controlled as mutually exclusive functions.
