STHS34PF80 Infrared Human Presence Sensor Module 3.3V–5V

STHS34PF80 High-Sensitivity Infrared Human Presence Sensor Module

The STHS34PF80 Infrared Human Presence Sensor Module is a compact, high-performance sensor designed to detect human presence and static motion with exceptional sensitivity. Powered by STMicroelectronics' STHS34PF80 chip, this module operates across a wide supply voltage range of 3.3V to 5V, making it a versatile addition to microcontroller projects, automation systems, smart home setups, and computer-interfaced applications.

Unlike standard PIR sensors that only detect motion, the STHS34PF80 can sense stationary human presence — ideal for occupancy detection, energy-saving automation, and intelligent control systems. Its SMD package format and customizable configuration make it a go-to choice for engineers, hobbyists, and embedded system developers alike.

Frequently Asked Questions

Q: What makes the STHS34PF80 sensor module different from a standard PIR motion sensor?

A: Unlike conventional PIR sensors that only trigger on movement, the STHS34PF80 infrared sensor module can detect stationary human presence — meaning it registers a person who is sitting still or not moving. This makes it significantly more reliable for occupancy-based automation, smart lighting, and energy-saving systems where static detection is critical.

Q: What microcontrollers or platforms is this sensor module compatible with?

A: The STHS34PF80 module supports a 3.3V–5V supply voltage range, making it compatible with a wide variety of popular platforms including Arduino (Uno, Nano, Mega), Raspberry Pi, ESP32, ESP8266, STM32, and most other 3.3V or 5V microcontroller boards commonly used in DIY and professional electronics projects.

Q: Can this sensor module be customized for specific detection sensitivity or range?

A: Yes — the STHS34PF80 module supports customizable configuration, allowing you to adjust detection thresholds and sensitivity parameters to suit your specific application requirements, whether for close-range desk occupancy detection or wider room-scale presence sensing.

Q: What is included in the package?

A: Each order includes 1 x STHS34PF80 High-Sensitivity Infrared Human Presence Sensor Module. The module is brand new and ready for integration into your electronics project.
