The SparkFun Qwiic Mini dToF TMF8820 Imager is a direct time-of-flight (dToF) sensor that includes a single modular package with an associated Vertical Cavity Surface Emitting Laser (VCSEL) from AMS.
The dToF device is based on Single Photon Avalanche Photodiode (SPAD), time-to-digital converter (TDC) and histogram technology to achieve a 5000mm detection range. Due to its lens on the SPAD, it supports 3x3 multizone output data and a very wide, dynamically adjustable field of view. A multi-lens-array (MLA) inside the package above the VCSEL widens up the FoI (field of illumination). All processing of the raw data is performed on-chip and the TMF8820 provides distance information together with confidence values on its I2C interface. The high performance on-chip optical filter blocks most of the ambient light, and enables distance measurements in dark and sunlight environments.
