Overview

The TMF8701-1BM is a high-performance Time-of-Flight (ToF) distance sensor integrated with an ARM Cortex-M0 core for high-speed histogram processing. Operating at 940nm, this 12-SMD module provides accurate proximity sensing and distance measurements from 2.7V to 3.3V, featuring dynamic cover glass calibration to maintain reliability behind protective materials.

Why Choose This Part

The integrated histogram architecture enables superior detection performance even in the presence of smudges or dirt on the cover glass. Its low-power architecture is notable, with a shutdown current of 0.26uA and a dedicated ARM Cortex-M0 core for offloading ranging algorithms from the host processor.

Applications

Presence Detection
Triggering system wake-up or power-saving modes when a user approaches or leaves a device like a laptop or smart appliance.
Collision Avoidance
Providing short-range spatial awareness for consumer robotics and vacuum cleaners to prevent impacts.
Gesture Control
Enabling touchless user interfaces for smart home panels, industrial controls, or sanitary dispensers.
Level Sensing
Monitoring fill levels in containers or dispensers where non-contact measurement is required for hygiene or maintenance.
