We are proud to have our latest sensor technology featured in an Embedded Computing Design article about the advantages of using radar sensors over passive infrared technology for security applications.
In my recent guest post on Embedded Computing Design, I discuss why radar sensors are poised to overtake the commonly used passive infrared (PIR) technology in security devices. I highlight two compelling reasons behind this assertion. First, recent advancements have made radar sensors smaller and more cost-effective to produce. Second, radar technology overcomes several shortcomings of PIR while also providing distinctive attributes.
A few of the advantages of radar technology are:
- Invulnerability to environmental conditions (e.g., smoke, fog or dirt)
- Ability to handle multiple data types
- No physical lens required (allowing for hidden sensors)
- Resistance to external heat
- Competitive pricing based on features
Socionext 24GHz Sensor Technology
For the above reasons as well as others mentioned in the article, it is clear that radar sensors will power next-gen security products. To meet these needs, Socionext has created a lineup of 24GHz ultra-low-power radar sensors designed to make it easy for manufacturers to add sophisticated sensing capabilities to their security and IoT products. Our newest devices feature multiple antennas (both Tx and Rx) integrated into a single compact 9mm X 9mm X 1mm package. They support CW, FSKCW, and FMCW sensing modes, and require only 2mW average power at 0.5 percent duty cycle to operate.
The Socionext 24GHz radar sensor lineup includes:
SC1233AR3 All-in-one 24GHz Radar Sensor for Entry Motion & 2D Detection
The SC1233AR3 is an easy-to-use, all-in-one 24GHz radar sensor that enables entry motion and distance detection without the need for external MCU. When paired with an MCU, the sensor can also perform 2D angle detection.
SC1232AR3 All-in-one 24GHz Radar Sensor for Entry Motion & Distance Detection
The SC1232AR3 is also an easy-to-use, all-in-one 24GHz sensor offering very low power operation and a wide detection area. The device adds distance detection without the need for an external MCU.
Both the SC1233AR3 and SC1232AR3 24GHz radar sensors feature a wide detection area and are well-suited for battery operation with a 0.5mW average operating power requirement for human detecting applications (0.1% duty cycle). Each is an ideal solution for smart home devices, security/surveillance, and home appliance applications.
