TMF8801 Time of Flight distance sensor breakout with a measurement range from 20mm to 2.5m and an update rate of approximately 30Hz. It uses a Class 1 940nm VCSEL, SPAD detector, I2C interface and STEMMA QT / Qwiic connectors, while onboard regulation and level shifting allow operation with 3–5V systems. Adafruit 6522
Description
The distance sensor breakout Adafruit TMF8801 uses the TMF8801 device from ams OSRAM for Time of Flight distance measurement. The sensor determines distance by measuring the return time of a short light pulse reflected from a target and provides a measurement range of approximately 20mm to 2.5m. Its narrow sensing cone makes it suitable for robotics, presence detection, interactive devices and applications requiring distance measurement directly in front of the sensor.
The TMF8801 uses a 940nm VCSEL Class 1 light source together with a SPAD detector. It operates at approximately 30Hz and provides a 24° field of view. On-chip histogram processing together with sunlight rejection filtering and algorithms help maintain measurement performance under changing ambient lighting conditions.
Communication is provided through I2C. The Adafruit breakout includes an onboard voltage regulator and logic-level shifting, allowing use with microcontrollers and single-board computers operating at 3.3V or 5V. Two STEMMA QT / Qwiic connectors provide solderless I2C connection.
The sensor requires a firmware patch to be loaded during startup, while SRAM usage remains low enough for use with resource-constrained microcontrollers such as the ATmega328. Arduino and CircuitPython/Python libraries and examples are available from Adafruit.
