He further explains that, with the Arduino Uno, you can remove the reference capacitor from the circuit, and simply use the stray capacitance present in the board and microcontroller, which can be ...

Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front ...

Diode-bridge type capacitance detection circuit was developed in order to detect very small variation of differential capacitances in higher resolution. The circuit was designed for a comb structure ...

Connect the Soil Moisture Sensor to the ESP8266 (or Arduino): Capacitive Soil Moisture Sensor: VCC: 3.3V on ESP8266 or 5V on Arduino GND: GND AOUT (Analog Output): Connect to an Analog Pin (e.g., A0 ...

Enhancing the sensitivity and resolution of the readout circuit is a pivotal technological approach to extending the detection range of capacitive proximity sensors (CPSs). This article introduces a ...
