Guest columnist Helen Francis, product marketing manager at Atmel Touch Technology, says that capacitive touch can be used as a proximity sensor In recent years, capacitive touch technology has ...
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-edge ...
The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...
CAMARILLO, Calif.--(BUSINESS WIRE)--Semtech Corporation. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the SX9300, an ultra-low power capacitive ...
I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
SICK, one of the world’s leading manufacturers of sensors, safety systems, machine vision, encoders and automatic identification solutions for factory and logistics automation, announced the launch of ...
This project is a simple modification of the LightGauge project. Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino.
