Explanation:
Motion sensors can be interpreted independently represents a measure of change in motion that can be a vector and / or velocity of an object or an object in a field of view where there is a physical interaction between mechanical equipment with a field of view. From this point, we will determine what the desired outcome interaction. What about Motion sensor outdoor lighting?
Halogen Motion Sensor Outdoor Lighting
I am sure, that depart from our understanding of the motion sensor. Motion sensor outdoor lighting gives an indication to us that there is an interaction between a motion sensor to a situation out there where the activation of a light beam is expected.
Motion Sensor Outdoor Lighting is very useful for those requiring a light beam. This motion sensor can be used as a light alarm that can give a surprise to people who are not invited to that are in your yard.
Even the motion sensor outdoor lighting will help you when to go home at night, carrying a lot of shopping items in your hands, with low light conditions. Well, you know what is meant by it.
Motion Sensor Outdoor Lighting is one type of alarm circuits that is widely available market price of about $ 40. However, on this occasion will be explained in a fundamental fact about what is in a motion sensor outdoor lighting box, so you can be a little bright on this.
Motion Sensor Switch Circuit
The main components of a motion sensor outdoor lighting is a Passive Infrared (PIR transducer), BS170 Mosfet transistor as the high-gain amplifier (switch), Relay 12V DC as the AC power switch and some diodes, resistors, electrolytic capacitors, and input / output AC terminals to the lamp.
Motion Sensor Outdoor Lighting-Switch
Select a PIR sensor unit in accordance with the required sensing distance, you can contact the nearest vendor, select ready-made box type. Relay type is selected in accordance with the lamp load. However, this also will affect the transistor mosfet as a switch. Since this is aimed at light load, then you need to modify the power transistor.
In a test using 12V DC lamp types. If the motion sensor circuit is functioning as you need to put a PIR motion sensor module by considering the source of motion, for example, regarding human height and adjust the height placement module.
Each time the PIR module detects movement of a living body. The output relay and switching mosfet in the circuit is switched to the part through 150 Ohm resistor and associated components. As a result, the relay on the output transistor is switched on and the lights get power supply through a relay (RL) contacts.
Motion sensor outdoor lighting is only, as an illustration, not recommended for those of you do not have enough knowledge of electronics, because this will your safety concerns related to AC power.
