Abstract

Oyster mushroom cultivation is very popular among rural and urban communities, both on a small, medium and industrial scale. Oyster mushroom cultivation requires controlling temperature and humidity in mushroom kumbung to get optimal mushroom body growth. In the fruiting body formation phase requires a temperature between 27⁰C-29⁰C with humidity between 70%RH-90%RH. Along with the rapid development of technology, currently monitoring and controlling temperature and humidity can be done automatically remotely using the NodeMCU ESP8266 based on the Internet of Things. Measurement of temperature and humidity using the DHT22 sensor. The acquisition of measurement data is sent to the ANTARES platform using an internet-connected ESP8266. Monitoring temperature and humidity can be seen on ANTARES. Temperature and humidity control using a 12 Volt DC water pump. When the measurement results exceed the desired temperature range and the humidity is less than the desired range, the pump will turn on to stabilize the temperature and humidity again. From the results of testing the tool, it is obtained that the appropriate measurement results are obtained and the pump also turns on if the temperature and humidity are not as desired.

Abstract

The stability of the power supply is very important for keeping telecommunications infrastructure running smoothly. Problems with the power supply can cause network devices to lose service quality and even stop working. This study is on the development of an Internet of Things (IoT)-enabled Automatic Transfer Switch (ATS) system that can monitor and manage electrical resources in real-time over the internet. An ESP32 microcontroller, a Wi-Fi module, a ZMPT101B AC voltage sensor, an ACS712 current sensor, a DC voltage sensor, and an ADS1115 ADC were all put together to make the system more accurate. The Nuxt framework was used to construct a web interface that shows measurement data provided to the Firebase Realtime Database. The test results show that the system can consistently transition resources between the power grid and a Solar Power Plant. The error rate for AC voltage measurements is less than 2%, and the error rate for DC voltage measurements is less than 1%. The IoT-based monitoring system also has an average connection delay of 2 to 3 seconds, which is still acceptable for monitoring power supplies in telecommunications systems. The proposed system could be used as an intelligent power management solution for small to medium-sized telecommunications networks.
