Panel size: 32mm * 24mm

Angle sensor: 100° cone angle

Working temperature: -15- + 70 degrees

Lens size sensor: diameter: 23mm (default)

Description:

1. The induction module is about one minute after the power initialization time, and the interval to the output module in the standby mode is 0-3 times per minute.

2. Avoid direct light, such as interference sources close to the surface of the lens module, so as not to cause the introduction of interference signal generator; avoid wind flow in the use environment, the wind sensor will also cause interference.

3. The sensor module uses dual probes. The window of the probe is rectangular, with double ends (one millionths per million) in the direction of both ends. When the human body passes through from left to right or from right to left, the dual infrared time is reached. , The greater the distance, the more sensitive the sensor, when the human body from the front to the probe or from the top

Reaching the bottom or passing from the bottom to the top, the dual infrared does not detect the distance change, there is no difference, the sensor is not sensitive or does not work; therefore the sensor should be installed in the bidirectional direction of the probe related to human activities, and as parallel as possible In the maximum direction to ensure that the human body has been passed by the two-way sensor probe. In order to increase the angular sensing range, the module uses a round lens. The probe is also meaningful on all four sides, but it is still higher than the sensing range of the up, down, left, and right directions, and the sensitivity is strong. It is still possible to meet the above installation requirements .vcc, trig (control end), echo (receiving end), gnd

4. Size and adjustment:

Note: The potentiometer adjusts the distance clockwise, the sensing range increases (about 7 meters), on the contrary, the sensing range decreases (about 3 meters). The delay adjustment potentiometer rotates clockwise, the sensor has a longer delay (about 300s), on the contrary, the induction delay time is short (about 5s).
