Security Light & Switch with PIR Sensor

The SB0061 is a pyroelectric sensor module designed for human body detection. It integrates a PIR (Passive Infrared) detector with a Fresnel lens on a compact printed circuit board (PCB), along with an analog integrated circuit (IC) identified as SB0061 and a limited number of additional components to create the module. The sensor provides a high-level output of 3.3V with a pre-settable variable width ranging from 5 seconds to 18 minutes.

The SB0061 pyroelectric sensor module operates based on the principle of detecting infrared radiation emitted by human bodies. The PIR detector is sensitive to changes in infrared levels, which occur when a warm body moves within its field of view. The Fresnel lens enhances the detection range and sensitivity by focusing the infrared signals onto the PIR sensor.

The compact PCB design of the SB0061 facilitates easy integration into various applications, such as security systems, automatic lighting controls, and occupancy sensing in smart homes. The analog IC processes the signals from the PIR detector and converts them into a usable output.

The output level of 3.3V is suitable for interfacing with microcontrollers and other digital systems, providing a straightforward method for triggering actions based on motion detection. The variable width output feature allows users to customize the duration for which the output remains high after detecting motion, ranging from 5 seconds to 18 minutes. This flexibility is particularly advantageous in applications where different response times are desired.

The circuit diagram of the PIR motion sensor module typically includes the PIR detector, Fresnel lens, analog IC, power supply connections, and output connections. Additional components may include resistors, capacitors, and possibly a transistor for signal amplification or switching. The overall design ensures reliable performance in detecting human presence while minimizing false alarms, making it an effective solution for various sensing applications.SB0061 is a pyroelectric sensor module,developed for human body detection.
