FR58L4LS-2020M-2
FR58L4LS-2020M-2 referred to as 2020M is a high-performance and low-power 5.8G radar sensor launched by Ferry Smart. The radar module uses the Doppler principle to transmit high-frequency electromagnetic waves through the antenna and receive the initial reflected waves to determine the objects within the coverage area. movement, giving the corresponding electrical signal. The module size is 20*20MM. The module integrates 5.8G microwave circuit, intermediate frequency amplifier circuit and signal processor. It has high integration and good production consistency. The module has a built-in 32-bit MCU and transceiver antenna, which greatly improves the sensing performance of the sensor.
The radar module has a long sensing distance, a wide angle, no dead zone, and the lens and lens aging problems are not affected by temperature, humidity, airflow, dust, noise, brightness and darkness.
The rain filter leaf algorithm is implanted in the module, which can filter out the false triggering of rain leaves, and has stable performance. It is widely used in smart lighting, smart security and other fields.
The module uses a low-power design, and the operating current is 3.6mA when a moving object is detected; it will automatically enter the sleep mode when no one is present, and the current is 70uA during sleep.
