Raspberry Pi based automatic temperature measurement and logging system for solar thermal purposes

For automatic temperature measuring and logging purposes in solar thermal experiments, a single board computer - Raspberry Pi based and sensor system is proposed. Different data sets are observed for sensors, thermometers, and thermocouples and they are compared. The consistency of the automated temperature measurement system is also verified.

Rancang Bangun Sistem Monitoring Dan Pemberi Pakan Otomatis Ayam Anakan Berbasis Internet Of Things (IoT)

Farm is one of the largest food suppliers after agriculture. Many of the breeders do everything to improve the quality of their livestock. The usual way used by chicken farmers are by manual means such as temperature checking, and checking the availability of feed. Therefore it is necessary to create an automatic temperature monitoring and chicken feeding tool, which in this research based on IoTs (Internet of Things). It uses DHT11 sensors to measure temperature in cages, Arduino Uno and NodeMCU ESP 8266 as microcontrollers and blynk applications as temperature monitoring tools. It consists of several interconnected parts. Starting from the DHT11 sensor measuring the temperature, then sent to the microcontroller after it is processed, then sent to the blynk webserver so that it can be accessed and displayed by the monitoring application. While chicken feeding can be made easier using servo motor as a door feeder chicken that works with scheduling system, then for the availability of feed will be measured by the specified weight. If the weight reaches a number less than or equal to 400 grams, then the loadcell sensor will send a notification to blynk with the message . The result of this researchs can monitor the temperature in the cage and provide feed automatically even though it still not maximal.

Design and Implementation of COVID19 Safety Amalgamation

This article gives an explanation about constructing the system that helps in preventing the open out of the virus and also minimizes human association with possible and reduces costs associated with hiring employees for manual thermal screening and readings. Thus, automating the tasks such as automatic temperature screening, face mask detection using image processing methods, and automatic hand sanitizer dispenser with the help of the Internet of Things (IoT). In a world battling against novel coronavirus disease, technology has been a lifesaver. This amalgamate system has features like a quick and efficient contactless automatic temperature screening and automatic mask detection along with an automatic hand sanitization system which will be a prototype built at a reduced cost which will helpfully be ensuring safety for Corona Virus Disease (COVID19) Pandemic.

Greenhouse temperature control based on Fuzzy Logic

There is a close relationship between crop growth and the control of environmental variables, as well as irrigation and fertilizers supplied. This article presents a system for collecting a greenhouse temperature, capable of acting in the opening or closing window system as a regulator of this environmental variable. Controlling the temperature acting on the opening or closing of the windows is convenient, since it does not require additional fuel, resulting in an economical alternative. Regarding control algorithm, Fuzzy Logic was used as a correction temperature technique. The proposal can be a good option for greenhouses that are not automated yet, saving costs by moving from human-assisted monitoring to automatic temperature monitoring.
