Vad betyder rörelsedetektor?

Rörelsedetektorer reagerar på rörelse och om en oönskad gäst befinner sig i ditt hem skickar detektorn signaler till ditt larm som går igång. Rörelsedetektorer brukar också kallas för öga, rörelsevakt eller rörelsesensor. En infraröd (IR) rörelsedetektor går ett steg längre än så och använder sig av infraröd teknik.

What is an IR sensor?

The IR sensor or infrared sensor is one kind of electronic component, used to detect specific characteristics in its surroundings through emitting or detecting IR radiation. These sensors can also be used to detect or measure the heat of a target and its motion. In many electronic devices, the IR sensor circuit is a very essential module.

What are some examples of PIR sensors?

After that, a signal processor is used to understand the signal to obtain the required data. The best examples of PIR sensors are bolometer, Pyro-Electric Detector, Thermocouple-Thermopile, etc. PIR sensors are available in two types like thermal IR sensor and quantum IR sensor.

How do I connect an IR sensor to Tobi if arm?

In the hexagonal box of the if arm, place the read digital sensor block from the sensors palette and select IR sensor from the first drop-down and the pin to which it is connected in the second drop-down. If the sensor doesn’t detect any object in front, Tobi should say “no object detected”.

What are the parts of an infrared sensor?

An infrared sensor includes two parts namely the emitter & the receiver (transmitter & receiver), so this is jointly called an optocoupler or a photo-coupler. Here, IR LED is used as an emitter whereas the IR photodiode is used as a receiver. The photodiode used in this is very sensitive to the infrared light generated through an infrared LED.
