Function Description
The photosensitive function is on
 |  |
| When the ambient light is bright enough, the light will not automatically light up even if a moving object is detected | When the ambient light is lower than the preset photosensitive threshold, the light will automatically light up when the sensor detects a moving object |
 |  |
| After the moving object leaves, the sensor will enter the delay time when it cannot detect the moving object and keep the light on | After the preset delay time, the light will automatically turn off |
The photosensitive function is off
 |  |
| No moving objects can be detected, and the lamp goes out | When the sensor detects a moving object, the light\ automatically lights up at 100% brightness and enters the set delay time |
 | |
| After the delay time, when the sensor cannot detect any moving objects, the lamp will be off |

Precautions
- When installing the product, the antenna board is required to maintain a certain height from the metal plane. It is recommended that the antenna board be kept at a distance of 5-12mm from the metal plane. It should not be close to or touch the metal plane, otherwise, the product may not work properly!
- The product has a better penetration effect on plastic and wood. At the same time, avoid metal shielding in front of the antenna, which will reflect microwaves and affect the actual sensing effect;
- Installing glass in front of the antenna will cause electromagnetic wave reflection and penetration attenuation, which will reduce the sensing distance of the sensor; installing ceramics in front of the antenna will also produce penetration attenuation, the greater the thickness, the more serious the attenuation;
- 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 and cause false alarms. The recommended power supply capacitor is 470 uF; it is recommended that the power supply ripple be guaranteed within 100mV, and the ripple of 50mV is better;
- The signal output of the sensor, the load current capacity is weak, it may not be able to directly drive the back-end equipment.
- When multiple sensors are used in the same site, the spacing should be greater than 0.5m. It is recommended that the product installation spacing be greater than 1.5m. Too close installation distance may cause false alarms in individual cycles;
- Avoid high current circuit coverage on the antenna surface. The electromagnetic field generated by the circuit loop will interfere with the normal radiation of the antenna, causing false alarms or changing the sensing range;
- If the microwave sensor and wireless communication module (NB, Bluetooth, WIFI, 2.4G module) coexist in the application, the distance between the antenna of the Internet of Things module and the antenna of the microwave module should be increased in space. At the same time, try to shield or not receive the trigger signal of the microwave module when the Internet of Things module is communicating; microwave sensors or products with built-in microwave sensors will be interfered with by wireless routers. It is recommended to keep 1m away from high-power wireless communication equipment such as routers and wireless hotspots during installation. Above spacing
- The light sensor threshold is the test value in a sunny environment, with no shadows, and ambient light diffuse reflection conditions. The wavelength of light-sensing detection light covers 400nm~1100nm (including visible light, LED tube, infrared light band), the illuminance value detected by light-sensing may be different at different time periods and under different weather conditions;
- The antenna surface of the microwave sensor should be avoided facing the AC drive power supply, and at the same time as far away as possible from the rectifier bridge, transformer, switch tube, and other high-power devices of the drive power supply, so as to prevent the power frequency signal from interfering with the microwave module and causing false alarms;
- In the actual application environment of the electromagnetic wave emitted by the microwave sensor, the different reflectivity of the obstacle will bring about the different sensing range, which is a normal phenomenon;
- Product specifications and parameters may be upgraded without prior notice.
