Adafruit STHS34PF80 Library Build StatusDocumentation

This is the Adafruit STHS34PF80 infrared sensor library for Arduino.

Tested and works great with the Adafruit STHS34PF80 Breakout Board.

This chip uses I2C to communicate, 2 pins are required to interface.

Adafruit invests time and resources providing this open source code, please support Adafruit and open-source hardware by purchasing products from Adafruit!

About the STHS34PF80

The STHS34PF80 is an uncooled, factory-calibrated infrared motion and presence detection sensor. Key features include:

  • High Sensitivity: 2000 LSB/°C IR sensitivity
  • Long Range: Up to 4 meters detection without lens for 70x25cm objects
  • Wide Field of View: 80° field of view
  • Smart Algorithms: Embedded presence, motion, and ambient temperature shock detection
  • Low Power: 10 µA supply current at 1Hz ODR
  • Temperature Sensor: Integrated ambient temperature sensor with ±0.3°C accuracy
  • Flexible ODR: Programmable output data rates from 0.25 Hz to 30 Hz
  • Digital Interface: I²C and 3-wire SPI interface
  • Operating Range: 5 µm to 20 µm wavelength, -40°C to +85°C

Installation

To install, use the Arduino Library Manager and search for "Adafruit STHS34PF80" and install the library.
