Abstract:
A land quality measurement device comprises a central processing unit (CPU) (1), a power circuit (2), a frequency circuit (3), a GPS receiver (4), a slope measurement sensor (5), a pH sensor (6), a touch-screen driver chip (8) and a liquid-crystal display (LCD) power circuit (7). The power supply circuit (2), frequency circuit (3), GPS receiver (4), slope measurement sensor (5), pH sensor and touch-screen driver chip (8) are separately electrically connected to the CPU (1); the LCD power circuit (7) is electrically connected to the touch-screen driver chip (8); the CPU (1) is a model LPC2101 CPU.
