EasyDetek EDC114 Radar Senser

Product Information

The EDC114 is a microwave sensor module manufactured by Shenzhen EasyDetek Technology Co., Ltd. It has a wider field of view (FOV) and does not require a Fresnel lens, which eliminates the risk of aging of the lens. The sensor is not affected by temperature, humidity, airflow, dust, noise, lighting, and other environmental factors and has strong anti-interference ability. It can penetrate acrylic, glass, and thin non-metallic materials. The module has a built-in MCU and embedded multiple digital filtering algorithms with higher immunity. It also has a patented antenna and measures 20 x 20 mm in size.

The EDC114 operates at a frequency range of 5.75 GHz to 5.87 GHz and requires an input voltage of 5-12V. It has an output high level of 3.3V and an output low level of less than 0.5V. The sensor has a 3db beam angle and operates at a current of 19-25mA. The detection range of the EDC114 is between 4-6m, and it has an operating temperature range of -20…85°C.

The EDC114 is typically used in applications such as downlights, proofing, cast lights, tube microwave radar switches, panel lights, ceiling lamps, and more.

Product Usage Instructions

When using the EDC114 microwave sensor module:

1. Connect the power supply to the V pin and ground to the G pin.
2. Use the O pin for output or UART TX and the RX pin for UART RX.
3. Mount the sensor in the desired location and ensure that it has a clear line of sight to the area being monitored.
4. The EDC114 operates as follows:
   • If no moving object is detected, the lamp remains off.
   • When the sensor detects a moving object, the lamp automatically lights up at 100% brightness and enters the set delay time.
   • After the delay time, if the sensor cannot detect a moving object, the lamp goes out.
5. Ensure that the EDC114 is installed and operated with a minimum distance of 20cm between the radiator and the body to comply with FCC radiation exposure limits for an uncontrolled environment.

Application note

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 good penetration effect on plastic and wood. At the same time, avoid metal shielding in front of the antenna, which will reflect 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 wave 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 small ripple, especially the low-frequency ripple, which is easy to interfere with the work of the sensor, resulting in 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 false alarm or changing the induction range;
8. If microwave sensor and wireless communication module (Nb, Bluetooth, WiFi, 2.4G module) coexist, the installation spacing between IOT module antenna and microwave module antenna shall be enlarger 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 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 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, so as to avoid the power frequency signal interfering with the microwave module and causing false alarm;
11. In the practical application environment, the electromagnetic wave emitted by microwave sensor, the different reflectivity of obstacles will lead to different induction range, which is a normal phenomenon;
12. Product specifications and parameters may be upgraded without prior notice.
