IoT Devices – Proximity Sensors

A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the return signal. The object being sensed is often referred to as the proximity sensor’s target.     Different proximity sensor targets demand different sensors. The different types of proximity sensors are: Inductive, Capacitive, Ultrasonic, … Continue reading IoT Devices – Proximity Sensors »

IoT Devices – Infrared Sensor

An infrared sensor is an electronic instrument which is used to sense certain characteristics of its surroundings by either emitting and/or detecting infrared radiation. Infrared sensors are also capable of measuring the heat being emitted by an object and detecting motion. Many of these types of sensors only measure infrared radiation, rather than emitting it, and thus are known as passive infrared (PIR) sensors. IR … Continue reading IoT Devices – Infrared Sensor »

IoT Devices – Basics of Sensors

Sensors are the eyes, ears, and skin of the Internet of Things (e.g. infrared, sound, temperature, etc.). There isn’t IoT without sensors. They are not about connecting devices. They are about improving the way of life, doing business, and the impact on the environment.   What is a sensor? A sensor is a device that detects and responds to some type of input from the … Continue reading IoT Devices – Basics of Sensors »
