The SparkFun Qwiic Mini Human Presence and Motion Sensor, featuring the STHS34PF80 Low-power, high-sensitivity infrared (IR) sensor from STMicroelectronics, is designed for precise presence and motion detection. This compact breakout board measures just 1.27cm by 2.54cm and includes two I²C Qwiic connectors, simplifying integration without the need for soldering. However, 2.54mm-spaced pins are also available for breadboard use.Ideal for applications such as alarm systems, anti-intruder setups, smart lighting, and room occupancy monitoring, the STHS34PF80 sensor measures black-body radiation and ambient temperature within its 80° field of view. It employs a matrix of floating vacuum thermal transistors to differentiate between stationary and moving objects, effectively eliminating self-heating effects. These features make it a versatile tool for various detection needs.Operating efficiently in diverse lighting conditions, the sensor is unaffected by visible light, thanks to its 5 to 20µm optical band-pass filter. With output data rates ranging from 0.25 to 30Hz and a single-shot mode accessible via I²C or SPI interface, it provides reliable performance across different environments.The SparkFun Qwiic Connect System is a streamlined ecosystem of I²C sensors, actuators, shields, and cables designed to expedite prototyping and reduce errors. All Qwiic-enabled boards feature a 1mm pitch, 4-pin JST connector to minimize PCB space requirements and ensure correct, polarized connections.Features:Breakout Board * Dimensions: 2.54cm x 1.27cm * Two Qwiic Connectors * I²C Address (7-bit): 0x5A (Default) * Two Mounting Holes: * 4-40 screw compatible * Six PTH Pins * 3V3, GND, SCL, SDA, CS, INT * Power LED (Red) STHS34PF80 Features * Voltage Range: 1.7 to 3.6V * Current Draw: 10µA * Interfaces: I²C or SPI * Optical wavelength: 5 to 20µm * Range: 4m (objects 70 x 25cm² in size) * Built-in Detection Algorithms: * Identify stationary objects * Distinguish between stationary and moving objects * Field of View: 80° * Output Data Rate: 0.25 to 30Hz * IR sensitivity: 2000 LSB/°C * RMS noise: 25 LSBrms * Operating Temperature: -40 to 85°C (default gain mode) * Sensor accuracy: ±0.3°C (local) * One-shot mode * Factory calibrated Documents: * Schematic * Eagle Files * Board Dimensions * Hookup Guide * Arduino Library * Component Datasheets: * STHS34PF805 Product Page * STHS34PF805 Datasheet * Qwiic Info Page * GitHub Hardware Repo https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-01-24 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-09-28 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-10 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-17 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-23 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-31 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-07 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-09 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-12-03 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-12-13 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-12-19 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-09 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-23 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-25 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-31 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-02-05 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-02-11 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-02-24 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-05 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-10 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-24 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-04-01 https://elecena.pl/product/27751448/sparkfun-mini-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-04-13
