Abstract

Abstract— DVOR (Doppler VHF Omnidirectional Range) equipment is very sensitive to room temperature. If the temperature is not between 18 °C to 24 °C then the DVOR Navigation device can be extinguished. The purpose of this study was to design a DVOR Navigation shelter temperature and humidity monitor using LoRa (Long Range) delivery and displayed in a web server. The study used a DHT 22 as temperature sensor, RTC DS 3231 to retrieve time data, a Micro SD Card module used to store data, LoRa as a data transmission medium, and ESP32 as a microcontroller. The study successfully designed and developed a temperature monitoring instrument using the DHT 22 sensor. The device is capable of measuring temperature and being sent according to delivery time as well as storing data to the SD Card via LoRa and displayed in the form of a web server. The results of observations showed that data transmission must be no obstacle or LOS (Line of Sight) in order to get good data.

Abstract

When consuming lake water for sanitation purposes, information about the quality of the lake water consumed is needed or not. The design and manufacture of this lake water quality monitoring device aims to provide information on the feasibility of lake water used for sanitation purposes. This tool uses the parameters of temperature, pH, TDS and turbidity level. This water quality monitoring device uses ESP 32 as its microcontroller by using a temperature sensor, pH sensor, TDS sensor and water turbidity sensor. The results of measuring lake water quality will later be displayed on the OLED screen and also displayed on the Blynk android application.

Abstract

Exhaust emissions can cause air pollution. Carbon monoxide is one of the air pollution comes from motor vehicle gas emissions. From current technological developments, low-cost gas sensors have been widely used. In research, data acquisition devices have been successfully developed using the MQ-7 sensor, ESP32, micro SD card, TFT display, and keypad. The results of the sensor calibration get 10 motorcycle data with a coefficient of determination (R2) of 0.9273 with a percentage of 92.73%. The average accuracy of the MQ-7 sensor is 91.23% with an error percentage of 1.82% and an RMSE of 0.379. From the results of the sensor calibration, it can be seen that the MQ-7 sensor has a fairly good level of accuracy. From field test, 30 motorcycles has been test. From the results of the field test of 30 motorcycles, factors that affect the value of carbon monoxide gas in motorcycles include dirty air filters, fuel used, and motorbike maintenance. As for the year of the vehicle does not affect the value of carbon monoxide gas.
