Overview

The TMF8805-1BM is a high-performance Time-of-Flight (ToF) distance sensor capable of measuring ranges from 20mm up to 2500mm. It integrates a VCSEL, an SPAD detector array, and a Cortex-M0 processor to provide accurate distance measurement with high ambient light immunity. The module operates over a 2.7V to 3.3V supply range and utilizes an I2C interface for host communication.

Why Choose This Part

The integrated Cortex-M0 core handles complex ToF processing on-chip, reducing the computational burden on the host microcontroller. Its modular OLGA12 package and built-in sunlight rejection filters ensure reliable performance even in challenging lighting conditions while maintaining a small 2.2mm x 3.6mm footprint.

Applications

Laser Detect Autofocus (LDAF)
Provides rapid and accurate distance data to assist camera systems in achieving sharp focus in low-light or low-contrast environments.
Presence Detection
Used in smart home devices or industrial systems to wake up high-power components when a user or object enters the sensing field.
Industrial Proximity Sensing
Enables non-contact object detection and distance monitoring in factory automation and robotics.
Collision Avoidance
Integrated into small mobile robots or drones to detect obstacles within a 2.5-meter range.
