Product Description:

Zrd-09 human body infrared sensor module adopts high-performance pyroelectric infrared sensor, Fresnel lens, pyroelectric chip, high-performance, voltage stabilizing circuit. It has the characteristics of low static power consumption, wide working voltage and high sensitivity. There are repeatable trigger and non repeatable trigger selection terminals, which can be set according to the actual needs, so it is convenient to use.

Product features:

1. Full automatic induction: when someone enters the induction range, input high level; when someone leaves the induction range, automatically delay to close high level. Output low level.

2. Photosensitive control (optional, not set in the factory): the module has a reserved position, which can be set with photosensitive control, and it will not be sensed in the daytime or when the light is strong. Photosensitive control is an optional function. Photosensitive resistance is not installed in the factory. If necessary, please contact the manufacturer to select photosensitive control.

3. Two trigger modes: l can't be repeated, h can be repeated. Jumper can be selected, default is h.

(1) Non repeatable trigger mode: after the induction output high level, the output will automatically change from high level to low level as soon as the delay time is over.

(2) Repeatable trigger mode: after the induction output high level, in the delay time period, if a human body is active in its induction range, its output will remain high level until the human leaves, and then delay to change the high level to low level (after the induction module detects each activity of the human body, it will automatically extend a delay time period, and the last activity time will be taken as the delay time) The starting point of the delay time).

4. With induction blocking time (default setting: 3-4 seconds): the induction module can set a blocking time immediately after each induction output (high level becomes low level), during which the sensor does not receive any induction signal. This function can realize the interval work of (induction output time and blocking time), and can be applied to interval detection products; at the same time, this function can effectively suppress all kinds of interference in the process of load switching.

5. Output high level signal: it is convenient to connect with various circuits.
