IoT-Ready Temperature Probe for Smart Monitoring of Forest Roads

Abstract

Currently, we are experiencing an ever-increasing demand for high-quality transportation in the distinctive natural environment of forest roads, which can be characterized by significant weather changes. The need for more effective management of the forest roads environment, a more direct, rapid response to fire interventions and, finally, the endeavor to expand recreational use of the woods in the growth of tourism are among the key factors. A thorough collection of diagnostic activities conducted on a regular basis, as well as a dataset of long-term monitored attributes of chosen sections, are the foundations of successful road infrastructure management. Our main contribution to this problem is the design of a probe for measuring the temperature profile for utilization in stand-alone systems or as a part of an IoT solution. We have addressed the design of the mechanical and electrical parts with emphasis on the accuracy of the sensor layout in the probe. Based on this design, we developed a simulation model, and compared the simulation results with the experimental results. An experimental installation was carried out which, based on measurements to date, confirmed the proposed probe meets the requirements of practice and will be deployed in a forest road environment.

A Low-Power Data Logger With Simple File System for Long-Term Environmental Monitoring in Remote Areas

“…for two months. A specially designed mechanical sensor system [40] referred to as DBAR was used for the installation. This is an original design of the sensor arrangement and its mechanical design to measure the vertical temperature profile of the soil crosssection [41].…”

Proposal of a Skin Temperature Measurement System Based on Digital Thermometers

“…Since our team has previous experience using DS18B20 digital thermometers, we decided to use this solution for application in the medical environment. In [18], our design utilizes 1-wire technology, which allows connecting multiple temperature sensors on a single twisted pair cable under certain conditions. The basis of 1-wire technology is a serial protocol that uses a data line and a ground reference for communication.…”

“…Subsequently, test the system in different aspects, taking into account for use in physiotherapy, where it could find a wide application in thermo-diagnostics, either as a primary or complementary method. Based on the review of available technologies and our previous experience with 1-wire based solutions [18]- [21], we chose the contact method using DS18B20 [22] digital thermometers as a measurement technology. Such sensors have various uses in temperature measurements [23]- [25].…”

Design of Remote Monitoring System for Lithium Battery Operating Statu

“…Thermocouple and MAX6675 are used for temperature collection. Thermocouple is a common temperature measuring device in the temperature collector, which can convert the temperature change into μ The V-level voltage signal [14] can be converted into the temperature value of the measured object through the relevant circuit. MAX6675 has the functions of cold end compensation, thermocouple disconnection detection, linearity correction, etc.…”
