How do microwave sensors work?

Microwave sensors utilize an MCU (Microcontroller Unit) to accurately calculate switch information and control the relay, turning it on at the zero crossing point of the sine wave to activate each load.
It is important to note that the conventional control mode is not the most effective way to handle the current surges generated when the sinewave high voltage is turned on.
This is especially true when dealing with large-capacity capacitors influenced by high voltage, which can damage the relay.
Various electrical loads, such as LED lamps, energy-saving lamps, and fluorescent lamps, all equipped with capacitors of different capacitances, further complicate the situation.
This poses a significant challenge for relays, as even a 50W LED lamp can generate surge currents ranging from 80A to 120A.
Ordinary relays with a capacity of 10A can only withstand three times the inrush current, which means they are likely to break within a few days or after a few occurrences.
Consequently, the conventional sensors available in the market have a short lifespan and are limited in handling small load currents.

What is a microwave sensor?

Microwave motion sensors are electromagnetic radiation motion-detecting devices that may be used to operate luminaires.
Microwaves work differently from PIR sensors, sending out microwave waves radiating off different surfaces and returning to a detector sensor.
The sensor can analyze this data to identify any movement within its range in less than 1/5 of a second.
Better versions of these operate in the 5.8ghz band, giving them better range and low interference,
