Because of unique water properties, humidity affects many living organisms, including
humans and materials. Humidity control is important in various fields, from production …

Direct interface circuits (DICs) are efficient for reading resistive, capacitive, or inductive
sensors in a digital format. The simplest DICs consist of just a few passive elements that …

In this paper, a new, simple and accurate impedance measurement technique (IMT) for wide
range lossy capacitive sensor is proposed. The proposed technique accepts sensors having …

This paper proposes and analyses a microcontroller-based interface circuit for inductive
sensors with a variable self-inductance. Besides the microcontroller (μC) and the sensor, the …

We present here the design and fabrication of a self-powered and autonomous fringing field
capacitive sensor to measure soil water content. The sensor is manufactured using a …

An outstanding event related to the understanding of the physics of mechanical sensors
occurred and was announced in 1954, exactly seventy years ago. This event was the …
