Pyroelektrischer Sensor – Wikipedia

These sensors have been used by a number of participants of the RoboCupRescue, but disadvantages are that the response time of a CO 2 sensor is very slow and the sensor has to be very close to the victim to provide useful data because it is very directional and depends greatly on air conditions such as humidity, temperature, wind, and dust. This makes it difficult to use in a disaster area ...

PIR Sensor: Overview, Applications and Projects - Latest ...

· PIR sensors are commonly used in security alarms and automatic lighting applications. Technically, PIR is made of a pyroelectric sensor, which is able to detect different levels of infrared radiation. For example, Everything emits varied level radiation and the level of radiation will increase with the increase of the object’s temperature.

Efecto Piroeléctrico | Piezoelectricidad | Cristal

El material cristalino que constituye un sensor piroelctrico genera una pequea carga elctrica cuando est expuesto a calor en modalidad de radiacin infrarroja. El cristal cambia si la cantidad de radiacin es notable, y tambin vara la carga. Entonces se puede medir con un dispositivo FET (siglas en ingls): transistor de efecto de campo, construido dentro del sensor. Son ms rpidos que los ...
