Microwave Proximity Sensor 'BSS300/BSS301'

**New Product** Microwave Proximity Sensor 'BSS300/BSS301' The 'BSS300/BSS301' is a sensor that uses radio waves (microwaves) to detect the movement and presence of people, vehicles, and objects without contact. In the current situation where contactless operations are required due to the COVID-19 pandemic, our new product can assist you! (Note: The BSS301 is scheduled for future release) **Examples of Use** - Gate (shutter) opening and closing sensor - Lighting activation sensor - Vehicle detection sensor - Collision prevention sensor - Water level monitoring sensor - Intrusion detection sensor, etc. **Features** - Usable in outdoor environments This sensor utilizes 24GHz band radio waves (microwaves). Microwaves are less affected by rain, snow, fog, and backlighting, which reduces false detection in outdoor environments and allows for effective use. - Selectable detection modes based on usage You can choose between two modes for detecting moving objects and stationary objects according to the usage situation, enabling detection tailored to the circumstances.

This sensor, as its name suggests, monitors the surrounding area and detects individuals who enter a detection zone of 0.5m to 20m. Other features include: ● Wide-angle monitoring of close-range areas It monitors with a beam width of approximately 52° horizontally and 45° vertically. ● High separation resolution of 20cm. This means it can distinguish between two closely approaching points or lines, detecting changes of 20cm. (Our conventional sensors detect at 2m.) As a result, even when emitting radio waves towards the ground, it can differentiate between the ground and intruders for monitoring. ● Strong against changes in the surrounding environment, such as weather, due to the characteristics of microwaves. Unlike conventional passive sensors used for close-range outdoor monitoring, it is not affected by temperature or weather changes. (Passive sensors detect people by receiving infrared radiation emitted from the human body.) Examples of installation for close-range sensors include: ● Pole monitoring ● Gate intrusion monitoring ● Building entrance intrusion monitoring, among others. Particularly in pole monitoring, it can complement the blind spots that occur at the feet of other intrusion monitoring sensors by monitoring from above towards the ground, allowing for a more seamless detection area to be established.

At Pal Giken, we are developing various sensors that use "microwaves," and this time we will explain how they detect intrusions. ◆◆ Two Detection Methods ◆◆ Our microwave sensors support two detection methods. 1) Beam Reflection Detection Method A single sensor is installed, and the transmitted wave output from it defines the detection area. The detection range depends on the antenna angle of the sensor, but the sensor alone covers a wide distance. When a target intercepts the transmitted wave from the sensor, it is received as a reflected wave and detected as an "intrusion." 2) Beam Interruption Method This method configures the detection area by positioning the sensor and reflector opposite each other. The transmitted wave output from the sensor hits the reflector and is received as a reflected wave. There are also products that configure the detection area using a transmitter and receiver. In this case, the transmitted wave output from the transmitter is received by the receiver. In both cases, the levels that serve as the basis for transmission and reception are monitored, and if the wave is interrupted due to an intrusion, causing the level to fall below a threshold, it is detected as an "intrusion."
