Electronic HW-M10 Neptune microwave radar modules HW M10 human body induction switch module

product parameters:

model: HW-M10

input voltage: 6-24V

output signal: 5V/0V

signal delay: 30s

sensing distance: 10m

first, the working principle of:

HW-M10 microwave induction module based on the Doppler principle using the planar antenna of high-frequency electromagnetic waves transmitted and received, and then detected inflection wave has a slight movement changes, in turn trigger microprocessor work, the final output useful control electrical signals (H-1/L-0) or control state (on/off, that is: on/off). This product is widely used in security monitoring, intelligent control system; Lighting appliance (garage, corridor, the road and other places of use).

Second, the main features:

1, not affected by temperature, humidity, air, dust, noise, light-to-dark and so on, strong anti-interference ability;

2, microwave module is a akin to the transmit and receive signals, wide coverage and non-blind-area;

3, in the transmission process in induction effect is relatively good in indoor use, better; When used outdoors, due to the environmental impact

the sensing distance slightly scaling-in or scaling or sensitivity slightly weaker phenomenon. This is a normal phenomenon, the user need not misgive;

4, design professionals, Planar Microstrip Antenna, low power consumption, in line with the ROHS environmental protection product high consistency.

Three, product application of wiring diagram

four, pay attention to matters:

● on power supply

it is recommended to use the DC regulated power supply, I .e., the output voltage, current ripple coefficient reached the target DC regulated power supply, otherwise it will affect the product's stability, there may be some exceptions, such as false positives, wu bao cycle and more pronounced, etc.

● On False positives

1, ensure that the power supply of the qualification, with reference to the first item;

2, the test, to ensure the products to be tested of the neighborhood has no moving object (induction range);

3, after power-on about 10s-30s initialization time during the period as in the ordinary induction, may result in false positives false;

4, in the indoor test, the induction is relatively sensitive, peripheral to remain static, and to ensure that the first sensing signal cycle after the conclusion of the next step of the test; Outdoor test, be sure to pay attention to the surrounding environment of the dynamics, such as birds, pedestrians, exchanges between the vehicles and the like;

5, the module output signal current is very weak, direct drive excessive power drive tube, may also be easy to cause false positives.

● Work delay adjustment

module back welding has had a [time] resistor for adjusting the delay time of the resistance, the greater, delay longer.

● sensing distance

module on the back there is only [distance] resistor for adjusting the sensing distance value, the greater, the farther the distance.

Note: This resistance value greater than those 3MΩ, may cause the circuit unstable! It is recommended that customers don't adjust this resistor, if necessary, please be sure to contact our staff.

● This product of the housing assembly

the metal shell is not susceptible to microwave penetration, this product should be avoid mounted within a metallic housing use. But such as plastic, ceramic, wood soil obstacles penetration effect is better. For more information, please refer to the test subject.

● This product of mutual time-harmonic

this product has a mutual resonance interference, so the effective induction range, to avoid the installation of two or more of the module, the mutual interference may affect your use of effect. If necessary, please be sure to contact our staff.
