Ultrasonic sensor comparison: HC-SR04, PING, Maxbotix

For many projects You will need to measure distance, let’s say You are building a robot and You don’t want to have it bouncing on the walls, aren’t You? One of the first ideas to get some orientation in surroundings is to use ultrasonic range sensor. We took three different sensors and do some basic […]

Hall effect sensor

Hall effect sensor is a sensor utilizing the Hall effect to measure magnetic field. Briefly speaking, it’s about diference in voltage charges within a conductor placed in magnetic field. CS3144E available in Nettigo store is a Hall effect sensor in TO-92UA package. It consists of voltage regulator, Hall voltage generator, differential amplifier and Schmitt trigger. […]
