EasyDetek EDC18D Radar Sensor

Product Description

The EDC18D module is designed based on the 5.8GHz Ultra Low Power Microwave Radar Induction Chip AT58LP1T1DB. This chip is based on the principle of Doppler effect development, using mature CMOS technology, highly integrated microwave transceivers, IF signal processing, and filtering on one chip. Because the adaptive calibration algorithm is integrated on-chip, the problems of in-band interference, out-of-band blocking, and environmental interference are effectively solved, and the reliability and practicability of the sensor are greatly improved. The EDC18D module is powered by the TM56M1511 power manage chip, and the microwave signal generated by the PLL inside the RF-IC (AT58LP1T1DB) is amplified by PA and radiated out through the ANT-TX antenna. The microwave signal will reflect when it encounters an object in the air. When the object is in motion, there is a certain frequency difference between the reflected signal and the transmitted signal. The reflected signal received by the ANT-RX is mixed with the transmitted signal to obtain the corresponding intermediate frequency information. MCU processes and analyzes the intermediate frequency signal, while MCU also continuously detects the CDS signal. Finally, the MCU determines the CDS signal and IF signal for final OUT output control.

List of applicable FCC rules
CFR 47 FCC PART 15 SUBPART C 15.249

Specific operational use conditions

1. During product installation, the module is required to keep a certain height from the metal plane. It is recommended that the module should be controlled at 5-12mm from the metal plane and should not be close to or touch the metal plane, otherwise, the product may not work normally!
2. The product has a good penetration effect on plastic and wood. At the same time, avoid metal shielding in front of the antenna, which will reflect the microwave and affect the actual induction effect.
3. The glass or ceramic in front of the antenna will bring reflection and penetration attenuation of electromagnetic waves and reduce the sensing distance of the sensor, and the attenuation will be more serious with the increase of thickness.
4. Please use the power supply with a small ripple, especially the low-frequency ripple, which is easy to interfere with the work of the sensor, resulting in a false alarm of the sensor. Recommended power supply output capacitance 470 UF; It is suggested that the power ripple should be within 100mV, and the effect is better when the ripple reaches 50mV.
5. The signal output of the sensor has weak load current capacity, and may not be able to directly drive the back-end equipment.
6. When multiple sensors are applied in the field, the recommended product installation spacing is greater than 1.5m. The installation distance is too close, which may cause individual cycle false alarms.
7. The antenna surface shall be protected from high current circuit coverage. The electromagnetic field generated by the circuit loop will interfere with the normal radiation of the antenna, resulting in a false alarm or changing the induction range.
8. If the microwave sensor and wireless communication module (NB, Bluetooth, WiFi, 2.4G module) coexist, the installation spacing between the IOT module antenna and microwave module antenna shall be enlarged and more. At the same time, try to shield or not receive the trigger signal of the microwave module during the communication of the Internet of Things module; Microwave sensors or products with built-in microwave sensors will be interfered with by wireless routers. It is recommended to keep a distance of more than 1m from routers, wireless hotspots and other high-power wireless communication equipment during installation.
9. The light sensor threshold is the test value under the conditions of a sunny environment, no shadow, and diffuse reflection of ambient light. The wavelength of light-sensing detection light covers 400nm ~ 1100nm (including visible light, LED lamp, and infrared light band). The illuminance value detected by light sensor may be different in different periods and different weather conditions.
10. The antenna surface of the microwave sensor shall avoid facing the AC driving power supply, and shall be far away from the rectifier bridge, transformer, switch MOSFET, and other high-power devices of the driving power supply as far as possible, to avoid the power frequency signal interfering with the microwave module and causing false alarm.
