Introduction

In the world of food industry, knowing the humidity level of raw materials, such as peanuts, is very important to maintain product quality. The right humidity can affect the taste, texture, and shelf life of peanuts. Therefore, the design of this peanut humidity detector is present as a practical solution that can be used both in the household and in factories. Peanut humidity detection is a crucial aspect of ensuring the quality of peanut products, and this article will discuss the design of a tool that can accurately measure humidity levels using DHT 11 sensors based on ATMEGA 8.

Benefits and Importance of Moisture Detectors

High humidity in peanuts can cause fungal growth, which is not only harmful to health, but can also reduce the quality of the beans themselves. By using this tool, users can measure moisture levels quickly and efficiently, so they can make the right decision whether the beans are suitable for consumption or need further drying. Moisture detection is a critical step in the processing of peanuts, and this tool provides a convenient and accurate way to measure humidity levels.

In addition, this detector also provides convenience in the processing of peanuts in the industry. For example, in a peanut factory, this tool can be used to ensure that every batch of peanuts produced meets the required moisture standards. This will help increase productivity and efficiency in the production process. Peanut processing is a complex process that requires accurate measurements of humidity levels to ensure the quality of the final product.

How Tools Work

The design of this tool utilizes the ATmega 8 microcontroller which functions as the brain of the system. DHT 11 sensor will measure the humidity and temperature of the environment around peanuts. The data obtained is then sent to the microcontroller, which then processes the information and sends it to the LCD screen for display. ATMEGA 8 microcontroller is a popular choice for many embedded systems due to its ease of use and affordability.
