HLK-LD020 5.8G Motion Sensing Module RaDAR Sensor 2.0/2.54mm Hole Spacing for Embedded Hidden Installation (5Pcs)

Description

• LD020 is a radar module operating at 5.8GHz. It adopts fixed-frequency, directional frequency, directional transmit and receive antenna (1TIR), integrated IF demodulation, signal amplification and digital processing functions, with delay settings, adjustable sensing range and light intensity detection and other capabilities.
• The module has the features of no wall penetration, anti-interference, small size, no wall penetration, high stability, good consistency, and good suppression of clutter and high harmonics.
• Short initialisation time and fast detection mode. Suitable for embedded hidden installation, not affected by temperature/humidity, oil smoke, water mist, etc., can be widely used in all kinds of mobile sensing scenes.
• Sensing Range: Hanging height 4-5m (sensing radius), wall-mounted 10-12m (radial). Sensing Angle: 110 10 (ceiling mounting).
• Power-on stabilisation time:5S(typ.). Delay time: 5S(typ.). Blocking time: 2S(typ.).
• Output voltage Vout: 3.3V(3.2~3.4V). Output current: <10mA. Operating Voltage:5V(5~12V). Operating current:1.8mA@VCC=5~12V(typ.)

HLK-LD020 5.8G Motion Sensing Module Radar Sensor 2.0/2.54mm Hole Spacing for Embedded Hidden Installation

Product Parameter
Frequency:5.8GHz(typ.)
Operating Voltage:5V(5~12V)
Operating current:1.8mA@VCC=5~12V(typ.)
Sensing range: Hanging height 4-5m (sensing radius), wall-mounted 10-12m (radial)
Sensing angle: 110 10 (ceiling mounting)
Output voltage Vout: 3.3V(3.2~3.4V)
Output current: <10mA
Power-on stabilisation time:5S(typ.)
Delay time: 5S(typ.)
Blocking time: 2S(typ.)
Operating Temperature:-20~+70

Attention:
The delay time is the time to keep the state after triggering, the default value is 5s;
Blocking time is the time to trigger again without response after the output state is flipped, the default value is 2s; and The default value is 2s;
Power on initialisation: after the module is powered on and the IO port output is high for 4s, the light is extinguished and then after another 3s to start the normal detection mode.

Tip Notes
Results may vary with different test environments or moving targets.
The metal casing has a shielding effect on electromagnetic waves, which affects the perceived distance.
There are errors in the sensing distance, and there will be uncertainty in the weak sensing area.
After switching on and off 3 times in a row during the test, it enters into the fast test mode on the 4th power-on, with a delay of 5s, and the distance defaults to the normal value.
After testing and power off, next time directly power on, the default into the normal mode of operation.
The above test results are in the standard test site test, the specific test environment, conditions, you can consult the relevant technical staff.
