Abstract
Micro climate (temperature, humidity and solar’s intensity) plays animportant role on growth anddevelopment of plants.However,it is difficult to obtainthemicro climate data continuously. An automatic data acquisition system is a such promising soluticts to this problem. The aimof this researchwas tomakemicro climate data acquisition system in real time and save it into computer’smemory. It consists of five stages included system design, sensor calibration, systemanalysis,data acquisition, and systemtesting. MicrocontrollerArduinoUNO based acquisition system designed has several inputs, i.e. three DHT11 temperature and humidity sensors and a light dependent resistor (LDR). The outputs of this system were displayed on the LCD, and on the PC using virtual instrument engineeringworkbench (LabVIEW) softwere, then the data were stored inMicrosoft Excel. The average error of temperature sensor for eachDHT11 comparedwith alcohol thermometer readingwas 0,8oC forbothDHT11-(a) and -(b), and 0,2 oC DHT11-(c). The average error of relative humidity (RH) sensor for each DHT11 compared with Cole Palmer’s termocopel was 14,63%for DHT11-(a), 16,63%for DHT11-(b), and 11,13%for DHT11-(c). The light intensity can be successfullymeasured using LDR voltage with an error of ± 8.98%and R of 0.9926.
