| Popis: | The monitoring system is used for know or get an information on a situation or condition in a certain place or area, with various methods used, so that many monitoring systems are developed and applied to assist human tasks in carrying out monitoring. The hardware design consists of 2 nodes namely the base node and the client node. At the base node there are 2 hardware components used, namely: Arduino Uno and the wireless communication module nRF24L01. The use of the NRF24L01 module is a reliable data communication module so that the data received is in accordance with the data sent by testing the module in different rooms and the same range with a distance of ± 800 m. Buzzer works well with temperature performance results ≥ 32 °C buzzer on and with ≤ 65% humidity buzzer on. The sensor network system can run well, because the ratio of the DHT22 sensor with the thermohygro, the average error is 1.4% for temperature and 3.8% for humidity from the results of data collection. |
