Physical Analysis of a Waterproof Temperature Sensor Responsiveness for Agricultural Applications

Abstract

This work analysis the responsiveness, accuracy and precision of a low-cost waterproof temperature sensor model DS18B20 and shows that simple procedures can allow these parameters analysis for other common temperature sensors. The water temperature is a parameter highly relevant for agriculture and aquaculture, and besides it has scientific, social and economic aspects that justify the present work, whose results are presented with quantitative parameters and justified according to solid measurement theories. This sensor has a digital design and requires only a very simple hardware to allow its connection to processors and, besides, it presented a very good accuracy and precision in the work tests.

Novel Technologies towards the Implementation and Exploitation of “Green” Wireless Agriculture Sensors

“…The deployment of agriculture wireless sensors [ 3 ] has revolutionized farming practices by providing real-time data which are crucial for optimal crop management. The most widely used sensors in agriculture are moisture/humidity [ 4 , 5 ] and temperature sensors [ 6 , 7 ]. Soil moisture sensors aid in precise irrigation scheduling, while temperature sensors help prevent frost damage and optimize growing conditions.…”
