The EKMC1603111 is a PaPIR motion sensor with a long detection range, a plastic lens, and a programmable output. It is a passive infrared (PIR) motion sensor that can operate as a human motion detector. It has a range of up to 12 meters and can detect movement with current usage of 170 uA. When motion is detected, the Motion 4 Click boardTM also includes a Toshiba TLP241A photo relay. This photo relay provides reinforced galvanic isolation for the external signals used to drive some external high-power electronic equipment. It is also featured on the Motion 4 Click boardTM. Due to low ON-state resistance, SSR connections can sustain 40 V while off and 2 A when on. The EKMC1603111 is supported by a library compatible with the mikroSDK and contains functions that make developing applications easier.

The EKMC1603111 has a detection performance of up to 12 meters at an ambient temperature of 25 degrees Celsius and a temperature difference of more than 4 degrees Celsius. The angle-detecting region has 92 detection zones, and it spans 102 degrees horizontally (51 degrees) and 92 vertically (46 degrees).

The output from the PIR sensor is fed into the buffer. Then it is sent on to the photo relay, which enables users to directly control with galvanic isolation electronic devices owned by the MCU, such as lights, motors, gates, and so on. The TLP241A photorelay can effectively replace mechanical relays that have traditionally been used, bringing up the complete set of benefits inherited from their predecessors. Some advantages include the lack of a bouncing effect on the output contacts, an almost infinite number of cycles because there are no moving parts to wear out, high resistance to mechanical shock and environmental influences, the low current required for activation, constant resistance because there is no carbon or rust that could build up on contacts, and the lack of sparking or an increase in body temperature when a person moves in front of a wall.

Then it will return to the temperature of the room again. The sensor detects a change in incoming infrared radiation when the output voltage changes. Same-temperature objects with varying surface characteristics may emit infrared differently.

As a result, shifting these objects about the background may also cause the detector to become activated. It is possible that motion parallel to the axis Z, such as moving back and forth toward the sensor, will not be detected in some circumstances.

Glass, acrylic, or similar materials that stand between the target and the sensor may not allow a correct transmission of infrared rays. Additionally, non-movement or fast movements of the heat source inside the detecting region can make it difficult to sense the heat source.

Frequently Asked Questions

What is the difference between a motion sensor and PIR?

The primary element that makes up a motion sensor is known as a pyroelectric sensor. Both people and other creatures give off infrared radiation, a sort of heat energy. A PIR motion sensor is equipped with two pyroelectric sensors that can detect the presence of heat energy in the environment around it. When they are heated or cooled, it contributes to the generation of an electrical signal.

How does a PIR motion sensor work?

Passive infrared, also known as PIR, uses a pair of pyroelectric sensors to identify heat energy sources in the surrounding environment. If the signal differential between these two sensors changes, the sensor will activate (such as when a new person walks into the room).

What is the advantage of a PIR sensor?

PIR motion sensors have the ability to detect moving objects with a high degree of accuracy, even when the room is completely dark. PIR sensors do not need to make physical touch with the objects being monitored in order to be able to detect motion caused by such entities. The installation process is straightforward, and there isn’t a lot of wiring that needs to be done. They make things operate automatically, which decreases the amount of work that needs to be done by humans. This is a good thing.

Does PIR work in the dark?

The simple answer is that it is. Motion sensors can detect movement even when it is dark because none of the motion sensors described above depends on the use of images to conduct their job. PIR motion sensors do not produce images but detect changes in the amount of infrared received.
