A data acquisition (DAQ) device had been developed and constructed for measuring temperature in agroforest production processes. The system configuration broken into building blocks performs different functions. A digital integrated circuits (LM35 temperature transducer), a AT89C51 microcontroller, MAX232 serial communication interface, DB-9 serial communication connector, ADC0804 analog digital converter, a 16-pin liquid crystal display (LCD) and 7805 voltage regulator were used in the design and implementation of the system. The software controlling the system adopted in the design is an embedded system structure encrypted in the microcontroller. The integration of the blocks circuit involved resulted in the complete functional temperature acquisition system. The performance test carried out under a simulated controlled environmental conditions satisfies the designed purpose.
