Alat Pendeteksi Kelembaban Pada Kayu Menggunakan dua Probe Sejajar Berbasis Nodemcu dan Iot

Abstract

One of the natural resources is wood. To increase the value of wood, in the industrial world, wood is widely used as a cooking utensil, home furnishings, building materials and others. The design of a wood moisture detector is to measure the moisture present in the wood. By using a conductivity sensor and NodeMCU as the driving brain of the tool and a power supply as a power supply, the conductivity method uses two probes connected to the wood being measured, then a signal processing circuit produces an output that shows the conductivity/electrical conductivity of the water. The value of some samples calculated by the designed tool is then compared with the value of the standard tool. The samples used were 6 different types of wood. The results of the measurements carried out are in the form of percent values and also calculate the deviation/accuracy value of the tool in detecting moisture from wood. The results of the calculation of the percent deviation obtained that the maximum value in sample 3 is 6.7% and the minimum value in sample 6 is 2.3% and the average value of the percent deviation of the six samples is 3.85%.
