HC-SR501 PIR Motion Sensor Module

TeknoCrafters FA3001 HC-SR501 PIR Motion Sensor Module The TeknoCrafters FA3001 is a versatile and reliable passive infrared (PIR) motion sensor module, based on the widely used HC-SR501 platform. It utilizes the LHI778 pyroelectric infrared sensor and the BISS0001 microcontroller to detect motion by sensing changes in infrared radiation. This module is ideal for applications requiring motion detection, such as security systems, automated lighting, and energy-saving devices. It is compatible with microcontrollers like Arduino, ESP32, and ESP8266. For Raspberry Pi users, an external analog-to-digital converter (ADC) is necessary due to the lack of native analog input.
