Features
The radar module has a long sensing distance, wide angle, no dead zone, and lens and lens aging problems are not affected by temperature, humidity, airflow, dust, noise, brightness, and so on. It is widely used in smart lighting, smart security, smart home appliances, smart home, vital signs and other fields. It can detect human micro-motion and breathing signals, realize living detection under human motion and static state, and realizing presence sensing .
Packing description
1. The module is packed in a blister box and placed in a blister box;
2. The blister boxes are stacked in a cardboard box according to 10 boxes;
3. The air raid in the carton is filled with instant noodles to reduce transportation abrasion;
4. Air bubble film is placed at the bottom of the carton to prevent abrasion during transportation;
5. The top layer is covered with bubble film and taped to prevent shaking.
Installation Precautions
· Avoid installing metal accessories or shells, metal will block the microwave and affect the effect;
· The antenna surface should be protected from high-current circuit coverage, which may cause interference;
· The output current of the sensor is very weak, and driving too large current is likely to cause false alarms. You can use the isolation drive method to drive the load, and use the OUT pin to read the status of the output port;
· Please use a power supply with low ripple for power supply, especially low-frequency ripples that easily interfere with the operation of the sensor. It is recommended that the power supply capacitor be larger than 100uF, and the recommended installation distance of the sensor is greater than 1.5m;
· The installation process of the product requires keeping the antenna board at a certain height away from the metal plane, and not close to or touching the metal plane, otherwise the product may not work normally;
· Avoid installing metal accessories or enclosures. Metal will block microwaves and affect the effect; therefore, this product should not be installed in a metal enclosure for use. However, the penetration effect is better for obstacles such as plastic, ceramics, and wood soil;
· Please use a power supply with a small ripple for power supply, especially low-frequency ripples are likely to interfere with the operation of the sensor. It is recommended that the power supply capacitor be larger than 100uF;
· The output current of the sensor is very weak. Excessive current driving is likely to cause false alarms. The load can be driven by an isolated driving method, and the output port status can also be read by MCU;
· When multiple sensors are used in the same site, it is recommended that the product installation distance be greater than 1.5m. Too close the installation distance may cause false alarms in individual cycles;
· The antenna surface should be protected from high-current circuit coverage, which may cause interference.
· Warning: The intermediate frequency signal output port (IFI/IFQ) is sensitive to ESD (electrostatic damage). Contact with high static electricity areas or power supply areas may cause irreversible damage to the radar module.
· Recommendation: It is recommended to use a qualified DC stabilized power supply, that is, a DC stabilized power supply whose output voltage, current and ripple coefficient meet the standards, otherwise it will affect the stability of the product and some abnormalities may occur, such as: false alarms, no Induction, circulation, self-starting, etc.
