AT58MP1T1RD (AT5812)

Low power consumption (9mA), direct output of control signals, suitable for applications with specific power consumption requirements.

5.8GHz series chips

AT58MP1T1RD (AT5812)

Product Features

Operating in the 5.8 GHz ± 75 MHz frequency band, this fully integrated microwave sensor chip features ultra-low power consumption (9 mA) and adopts an ultra-low-power architecture. The chip integrates a signal processor internally, enabling it to directly output sensing control signals. With just a few external components, it can easily form a complete microwave sensing sensor. This chip solution is the preferred choice for upgrading and replacing traditional non-fixed-frequency solutions, as well as the optimal option for reducing costs in conventional 5.8 GHz microwave sensing applications.

Application scenarios

• Smart Lighting
• Security & Surveillance
• Smart Healthcare & Wellness
• Home Appliances & Electronics
• Bathroom
