Abstract:
The objective of this study is to design and test a low-cost compost temperature and
moisture monitoring system. Using a soil moisture sensor to measure moisture and a
DHT22 sensor to measure temperafure, data was gathered over the course of a month.
The system was designed to give precise, in-the-moment monitoring in order to
maximize composting procedures. The temperature sensor's accuracy was verified
using a conventional thermometer, and the results revealed a high correlation
coefficient (R) of 0.9988, an RMSE of 0.9820, and an R' value of 0.9997. The
temperature measurements had an avetage error rate of 0.965 percent, which is very
good agreement with standard measurements. Similarly, an analysis was conducted to
compare the effectiveness of the soil moisture sensor with the oven drying technique.
The sensor's RMSE was 1 .6377 percent, its R2 value was 0.9868, and its strong
correlation coeffrcient (R) was 0.9948. A high degree of accuracy in tracking the
moisture content of compost was indicated by the average percentage error in the
moisture measurements, which came in at 2.682. These outcomes validate the lowcost
sensors' dependability and accuracy utilized in this investigation. The findings
imply that the devised system is a workable and reasonably priced compost monitoring
option, with potential uses in commercial and small-scale composting facilities.
