Design and Testing of a Monitoring System for Mushroom Planting Greenhouse

In order to realize intelligent control of mushroom planting's parameters of air temperature and humidity, lighting intensity, and temperature and humidity of soil culture materials, it carries out design with ZigBee network, and intelligent fuzzy control algorithm as core. With advantages of high precision and stability, the design of sensor circuit mainly employs digital module sensors. The closed loop control is realized by employing fuzzy control algorithm and the test result shows that the deviation of air temperature is controlled within ±0.8°C, the deviation of air humidity is controlled within ±9%, the deviation of lighting intensity is controlled within ±21 LUX, the deviation of temperature of soil culture materials is controlled within ±0.9°C, and that of humidity of soil culture materials is controlled within ±6%, thus all parameters fully meet practical requirements of mushroom planting greenhouse.
