AT89C51 -based soil temperature and humidity data acquisition and control system design
ot; multiplication, and transformation by the sensor circuit output voltage as a function of soil moisture content between 0 . Sensor probe is composed of a pair of needle-like stainless steel column , and easy into the soil , little effect on soil structure . AT89C51 and relay control system to control the motor to achieve the regulation of temperature and humidity , with similar traditional and modern test systems test system compared with the simple structure, small size , low cost, versatility and good features , which will help secondary development.
