Capacitive sensing is a versatile sensor technology and has proven itself in many different measurement and detection tasks [1]. The measurement principle is based on the capacitive coupling between ...

However, achieving high-precision liquid-level sensing is challenged by issues such as low resolution, limited sensitivity, poor stability, and high cost. In this study, a high-precision ...

A new capacitive liquid level sensing interface weak-capacitance detection ASIC has been designed. This ASIC realized the detection of the output capacitance of the capacitive liquid level sensor, ...

At present, there are mainly two types of capacitive pressure sensors based on ordinary capacitance and electrical double layer (EDL) capacitance. However, few researchers have combined these two ...

E → is the strength of the applied electric field, ε is the dielectric constant (which is unitless), ε 0 is the vacuum permittivity, and CH is the Helmholtz capacitance. μ and α are the derived ...

Capacitance sensors are used to experimentally measure different properties of the slug flow. I developed a simulation to capture raw capacitance data and calculate different characteristics of the ...

An ESP32 based water softener salt level sensor Uses the HC-SR04 ultrasonic distance sensor to measure the salt level in the brine tank. The level is published to an MQTT broker configured in the ...
