What are examples of motion detectors?
Motion detectors are: infrared detectors, ultrasonic, microwave, radiowave and... dogs.
What instrument measured heat?
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
Would an obese person be more or less sensitive to temperature change?
They would be more sensitive to heat and less to cold. The fat in your body acts as a 'coat' or jacket would. Imagine wearing heavy coat in the summer.
Can we experience heat without matter?
Yes. Energy radiated in the infra-red part of the spectrum can be felt without any intervening matter. However, you must still have the temperature sensitive nerves in your skin, or temperature sensitive equipment in your equipment and those will be made of matter!
Describe the uses of ionising radiation used in a home?
Smoke detectors
What do Photoelectric detectors detect?
Photoelectric detectors are more sensitive to slow, smoldering fires
What do dust detectors on space probes do?
protect sensitive equipment.
How can you detect a fire?
Fire detectors do not detect the presence of fire, rather they detect heat or smoke depending on the type of detector. Smoke detectors have a light inside which shines on a receiver when smoke is present in the room it rises up and causes a break in the light therefore activating the alarm, this also makes it common for false activations in these types of alarms due to dust and dirt in the air. Heat detectors on the other hand have a small plate on the outside which is temperature sensitive. Heat detectors can be reactant to different levels of heat depending on what their use it. Usually they are made to activate at around 185 degrees F. When the ambient temperature reaches this (very low temperature for a fire) the metal plate will melt off its contact points therefore activating the alarm. These are just two types of detectors.
Which zone is smoke or heat detectors?
The smoke or heat detectors have a 128 wireless zone. It is also stated that the detectors that have a 128 wireless zone also provide both real time and event scheduling capabilities.
What is the use of thermistor in fire alarm?
They are the central component in heat detectors which detect heat.
What is the distance between heat detectors?
5M Detector to Detector
Which zone is used for smoke or heat detectors?
panic zone
What is the most sensitive radar detector?
According to radardetectors.com, the Valentine is the most sensitive and most highly rated of all the radar detectors. It provides front and rear detection.
Can you use fire panel heat detectors as stand alone units?
no
Is the iPod Touch heat sensitive or touch sensitive?
The iPod Touch has a heat sensitive screen. If you touch one with cold fingers it will not work.
Will a zanco go off on a metal detector?
Airport metal detectors are quite sensitive to metals, this includes metal implants that may have been placed inside your body. Belt buckles, key chains, and steel-toed shoes may set off these sensitive metal detectors. Many commonly used orthopedic implants may also set off the metal detectors.
What instrument is used to detect infrared radiation?
Instruments for detecting infrared radiation include heat-sensitive devices such as thermocouple detectors, bolometers, photovoltaic cells, and photoconductors.Pranay karnatak
