Small Saturday project utilizing two ESP32 (NodeMCU), two HC12 433 mHz radio modules, one HC-SR505 mini pir sensor, and one HW-508 (or KY-006) passive piezo buzzer. The power supply can be realized ...

GreenPeak Technologies announced the expansion of its Smart Home portfolio with the addtion of a reference design for a low cost Passive Infra-Red (PIR) sensor with outstanding performance.GreenPeak ...

The project was done in IAR Workbench for MSP430 and Proteus simulation software. A Motion detector based alarm was developed using modules of PIR Sensors, LED's and Buzzer. They were controlled using ...

Reference design for low-power PIR detector to sense motion with wireless capability and approximately more than ten years of battery life. Automation systems use motion detectors to control functions ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...

Infrared Motion Sensor – Sensitive detector and integrated circuit for precise motion detection Adjustable Settings – Customise time delay, ambient light sensitivity, and detection distance Manual ...
