In normal mode the power consumption is about 26mA while 55uA in lower power mode. The module dimension is 30mm*7mm. The module adopts Airtouch's AT10LP1T1RDB which highly integrates the microwave ckt, IF amplifier and signal process unit, with embedded patch antenna which minimizes the overall module dimension with optimized performance and regulatory compliance. These features facilitates the applications in hand sweep induction switch, portable lighting and, camera wake-up fields. 2 Module illustration AT10LP1T1RDB MCU Sensing LED indication Antenna Plot. 1 AT10L4LDB-3007 module 3 Input output interface The module interface is through the 6 pins: V, G, O, P0, P1 and P2 with pin pitch supports both 2mm and 2.54mm. The sensing distance and delay time are adjustable by programming the MCU through the interface. Further the serial port can be used for registers configuration. Below table is the pin definition: Pin V G O P0 P1 P2 Function Power supply GND Output signal GPIO0 GPIO1 GPIO2 Remark Embedded LDO is on, supply voltage range is 3.5~12V If LDO is NC, supply voltage is 3.3V Output level (0V/3.3V) MCU programming port- ICSPCLK MCU programming port- ICSPDAT / serial port Tx (need to rework on resistor) Serial port Rx (need to rework on resistor) The output can be controlled by MCU (default) or by AT10LP1T1RDB. In MCU control mode, the output is alternated between logic high and low for every sensing. In AT10LP1T1RDB control mode, 1 AT10L4LDB-3007 10.525GHz Radar Sensor Module the output will be logic high lasting for a period and go back to logic low for every sensing. The setting for the 2 modes are illustrated in Plot. 2.

MCU control mode is by MCU programming. AT10LP1T1RDB control mode is by on-board resistors as below In Plot. 4, when pop'ed with 0R in red rectangle, the module is in normal mode (about 26mA); if they are removed, the module is in low power mode (about 180uA). Resistor in blue rectangle is for light-ON delay time setting. The resistor is NC, 0R and 2.4M ohm, the delay time is 30 seconds, 1.5 seconds and 63 seconds respectively. The delay time of a new sensing is prolonged accordingly during an existing trigger. Resistors in yellow rectangle (th0, th1, th2) offers 8-shift sensing distances. The resistor NC is logic 1 resistor 0R is logic 0. The truth table of the 3 resistors is in Plot. 5.The smaller value of threshold results in longer sensing distance.

The PD threshold can be adjusted by either register configuration or resistor value adjustment in PD ckt. When the environment is bright that the sensing is above threshold, the module won't sense anything. PD (NC) location Plot. 6 PD location 8 Module power-up sequence The module has a BIST. When powered up, GPIO output high for 2 seconds then switched to low for 1 second, then it enters normal sensing mode. Plot. 7 shows the power sequence: VCC GPIO 2S 1S in sensing and controlling mode Plot. 7 power-up sequence 9 Sensing distance The module's detection sensitivity can be adjusted by resistors. The maximum distance is 5 m. Below plot illustrates a typical detection range. If the threshold is set high, the detection range will be larger. In Plot. 9, dark zone means high sensitive areas that an fully detect movements. Light zone means low sensitivity which basically can detect movements but not always guaranteed. Plot. 9 detection range (Unit: m) 4 10 Attention AT10L4LDB-3007 10.525GHz Radar Sensor Module Metal should be avoided on top of the antenna under installation which would result in signal shielding. Plastic or glass is acceptable while distancing on top of the antenna should be maintained. Large metallic instruments or infrastructures should be avoided right to the radar antenna. Parallel arrangement should be maintained under multiple radar modules installment. 1m distance should be kept between modules. The module is not suggested in applications near power switches under low-power mode. 5 FCC Warning Please take attention that changes or modification not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
