3. HEAT SENSORS
Heat sensors are the ones that measure the temperature and send the information to a processor. This processor contains the principal information and decides if the temperature is the right one or not.
SENSORES DE
TEMPERATURA

4. LIGHT SENSORS
A light sensor is an electronic device that answers to the change of intensity of light. This sensors require a component which generates light transmitter and a receiver component that see the light that is generated by the issuer.

5. SMOKE SENSORS
A smoke detector is a safety device that detects the presence of smoke in the air and emits a signal warning of the danger of fire.

6. INFRA-RED SENSORS
Especially the infrared sensor is an electronic device capable of measuring the radiation electromagnetic infrared of bodies in your field of vision. All the body reflects a certain amount of radiation.

7. PRESSURE SENSORS Doors presion sensors,
They are based on piezoresistive technology to provide high independent precision of temperature. And the ability to direct digital communication with PC.

8. HUMIDITY SENSORS Most usual humidity sensors,,
Mechanical take advantage of the dimension changes that suffer certain types of materials en presence of humidity.
Capacitive based simply on the change of the capacity that a capacitor suffers in the presence of humidity.

9. SOUND SENSOR
This sensors can detected the enrgy produced by any type of sound, including the broken glass. This sensors can be founded in house alarms, or microphones.
