“…The utilization of logic elements (LEs) in the FPGA chip was found to be less than 1%, in which only 96 out of 114,480 LEs were used by the designed switching controller. In addition the execution speed of the designed switching controller using the FPGA chip was found to be 99.9% faster than the microcontroller (PIC16F877A) [41][42]. Thus, the switching controller designed in FPGA chip was found to be far more superior to the microcontroller [39][40].…”

“…According to Li et al [19], when the temperature is increasing, it also increases the occurrence of the outdoor environment in temperature. The ventilation fan with smart features, which uses a microcontroller to create an automation function is the best solution for the ventilation system [20]. The voice recognition using the Filipino language was used to automatically control the electric fan speed from speed no.1 to speed no.…”

Computer laboratory plays the role of key elements with high interest for different categories of populations. Event of fire, smoke, heat, and water leakage when occurs could cause a big loss for business continuity. This paper presents a developed system for internet of things (IoT) based smart fan controller and fire prevention in the computer laboratory. The aim was to develop an automated computer laboratory that would control and monitor the computer laboratoryenvironment from the incident of fire, heat, smoke, and water leakage. The system was created using three nodes and a single database. The first node used a flame sensor which detects fire and activates a fire extinguisher automatically. The second node used a digital humidity and temperature sensor (DHT), along with an ultrasonic sensor, which was used to manage a fan controller and activate the controller when the temperature is high and a person is present. Thirdly, smoke and water sensors were used to detect the presence of smoke and water leakage. Microcontrollers, access points, and software are used to accomplish the development of this system. Different actions of warning users were done. Triggering buzzers and sending emails were done whereas fire, smoke, and water leakage are detected. The email was also sent to the users registered in the system when there was a temperature of more than 25.

Increasing market demand cannot meet the needs of the community, especially in the rainy season, because Kroto produced by weaver ants is of low quality and hard to find. Modern Kroto cultivation has many advantages compared to traditional searching in nature. The quality and quantity of Kroto lie in maintaining the temperature and humidity for weaver ants. The challenge is how to maintain the temperature and humidity inside the artificial nest of weaver ants. To help overcome the problems of modern weaver ant cultivation, we design and develop automated devices based on the Internet of Things (IoT) to control and monitor temperature and humidity for weaver ant culture. We chose the limitation of temperature is in between 25 o C -31 o C, and the humidity range is on the level 65% -85%. We used NodeMCU as the mainboard, DHT22 as temperature and humidity sensor, Cayenne webserver as IoT platform, and fan, humidifier, and heater for the tools to control the environment. We had conducted four tests scenario, which are sensor calibration, relay testing, actuator time testing, and delay testing. The result in temperature reading shows good accuracy while the humidity performs a huge gap of error. The humidity needs to be adjusted with the linear regression formula. Based on the relay testing, the device works perfectly fine to control the heater, the humidifier, and the fan. According to the actuator timing testing, the humidifier has the quickest time to make more humid and soothing conditions, around 5 -15 minutes. In contrast, the heater actuator needs a longer time to heat up the room. Depends on the temperature, it needs around 5 -31 minutes. The longest time was during the fan actuator to cool down the room, around 30 -90 minutes. The average delay of the IoT system is 200,01 ms and is categorized as good performance based on standard TIPHON.
