Abstract

Cultivating bean sprouts requires regular care for the beans. The required care includes regular watering and maintaining temperature conditions between 23°C to 28°C with a humidity level of 85% to 90%. In this research, an intelligent sprout cultivation system based on LoRa and IoT has been proposed. This system uses a DHT22 sensor to read the temperature and humidity of the air around the bean sprouts. It sends the data to the gateway using LoRa. The gateway forwards the temperature and humidity data to the Thingspeak server using the MQTT protocol. LoRa allows temperature and humidity monitoring to be carried out via the LoRa local network without an internet connection. The proposed system can also water the bean sprouts automatically if the humidity is < 80% or the last watering time has been ≥ 3 hours. Based on the tests carried out, it can be concluded that the proposed system can work well. During the tests, the DHT22 sensor could respond to changes in temperature and humidity. Sending sensor data to the Thingspeak server could work well. Meanwhile, sensor nodes and gateways could communicate up to a distance of 600 meters using LoRa.

Abstract

Street lighting is one of the public facilities that plays a vital role in providing safety and comfort for road users. Therefore, any problems that occur with street lighting must be handled quickly and precisely. To achieve this goal, this study proposes a system for monitoring the condition of street lighting using LoRa-based multihop communication technology. In this study, each street light unit is equipped with an ACS172 current sensor and a BH1750 light sensor to determine the damage that occurs to the street lights automatically. Data from these two sensors is sent using LoRa Ra-02 to the relay and then forwarded to the gateway. The gateway forwards the data to the Firebase server so that the results of monitoring public street lighting can be observed via the internet network. Based on the results of system testing, the street light units (sensor nodes) can communicate with relays up to a distance of 200 m and with gateways up to a distance of 400 m. The gateway can also properly send sensor data to the Firebase server, so monitoring results can be viewed online via a smartphone.
