Long Distance 12M Detector Sensor HM412 From Senba Factory


Overview

Long distance pir sensor allows you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors.

FAQ
1.How long do motion sensor lights stay on?
Most people set their motion detection lights so they will stay on for about one to two minutes.

2.Do motion sensors save electricity?
Motion sensing switches do have some “phantom” energy use. According to this study, motion sensor switches use about a watt of energy on standby mode (23 hours a day) and 5 watts on active mode (about an hour a day). This trims a bit off of your overall savings.

The Application of the Idr Sensor

图片
1. Electronic photometry The photometer can be used to measure the brightness of people and objects, so as to help the photographer choose the appropriate exposure speed. The following is the schematic diagram of the electronic photometer. The ldr sensor  changes the intensity of light into the difference of resistance value, so that the brightness can be displayed directly by different currents flowing through the meter. Among them, R1 and R2 are used to adjust the surface calibration and W is used to control the sensitivity of the meter head. 2. Infrared thermometry The infrared light radiated by the measured object is modulated into 800Hz optical signal by a modulation disc with a filter, which is approximately sinusoidal wave. The modulated light entering into the idr sensor is converted into electrical signals and then sent to the FET amplifier for amplification. The output U0 can reflect the temperature. In order to reduce the influence of noise and temperature c...

Non Contact Thermometer

Non-contact temperature measurement solution The traditional body temperature measurement is a contact measurement using a mercury thermometer, which has the advantages of stable performance and small error, but has the disadvantages of long measurement time, high risk of cross-contamination, and easy to cause mercury poisoning due to glass breakage. Infrared ear thermometer is the most commonly used thermometer. N on contact temperature measurement sensors   can test body temperature with a slight amount of forehead or ear, and it can also prevent body infection. Infrared ear thermometer collects infrared radiation from ear cavity and tympanic membrane through infrared sensor. And converted into a digital signal, the main control CPU unit converts the digital signal into a temperature value and displays it on the LCD screen. Compared with mercury thermometers, infrared ear thermometers have the advantages of high precision, high resolution, fast measurement speed, easy op...
