Product Description

Human body infrared sensor module

Human body infrared sensor module

The module detects human activity through the principle of pyroelectricity. Once a person enters the detection area, the sensor will send a high-level signal. The Fresnel lens filter attached to the surface can improve the recognition sensitivity and reduce the effect of environmental interference. This module is often used in corridor switches, visitor notification devices, etc.

Product parameters:

VCC: power supply interface, can be connected to 3.3V, 5V

GND: Ground

OUT: Single bus digital signal output

NC: Empty interface, no need to connect

Working voltage: 3.3V/5V

Module size: 29.4mm*36mm

Sensing angle: 120°

Sensing distance: 8m

Model sensor: RDA224 digital pyroelectric sensor

Interface interface: interface interface, DuPont line interface, PH2.0 cable interface

Connection:

1. Alligator clip connection

(Recommended scenario: use of micro:bit motherboard or micro:bit expansion board)

2. Dupont line connection

(Recommended scenario: common connection methods such as Raspberry Pi and Arduino)

3. PH2.0 cable connection

(Recommended scenarios: common connection methods such as robot kits, sensor expansion boards, etc.)
