Built around the STHS34PF80 sensor from STMicroelectronics, this compact board (2.54 cm x 2.54 cm) empowers engineers to effortlessly experiment and develop applications. It features two Qwiic connectors, four mounting holes, six PTH pins (3V3, GND, SCL, SDA, CS, INT), and a red power LED.The STHS34PF80 sensor is adept at measuring precise black-body radiation and monitoring ambient temperature within its 80° field of view. Comprising a matrix of floating vacuum thermal transistors, it differentiates between IR-exposed and shielded segments to eliminate self-heating effects. Its algorithms can detect and distinguish between stationary and moving objects, making it ideal for alarm systems, anti-intruder setups, smart lighting, and room occupancy applications.Operating seamlessly in varied lighting conditions, the sensor is unaffected by visible light due to its 5 to 20 μm optical band-pass filter. With output data rates ranging from 0.25 to 30 Hz and single-shot availability, it interfaces via I²C/SPI, making it versatile for numerous applications.The SparkFun Qwiic Connect System simplifies prototyping with its ecosystem of I²C sensors, actuators, shields, and cables. Utilizing a common 1 mm pitch, 4-pin JST connector, it minimizes PCB space requirements and ensures polarized connections to prevent incorrect hookups.Features:Breakout Board * Dimensions: 2.54 cm x 2.54 cm * Two Qwiic Connectors * I²C Address (7-bit): 0x5A (Default) * Four 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: 10 μA * Interfaces: I²C or SPI * Optical wavelength: 5 to 20 μm * Range: 4 m (objects 70 x 25 cm² 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 30 Hz * 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: * STHS34PF80 Product Page * STHS34PF80 Datasheet * Qwiic Ecosystem * GitHub Hardware Repository https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-01-24 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-09-28 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-12 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-17 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-24 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-26 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-10-31 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-02 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-07 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-12 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-14 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-11-20 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-12-03 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-12-13 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2025-12-19 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-09 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-23 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-25 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-28 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-01-31 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-02-05 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-02-11 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-02-19 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-05 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-10 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-24 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-03-29 https://elecena.pl/product/27751423/sparkfun-human-presence-and-motion-sensor-sths34pf80-qwiic 2026-04-13
