Product description: Fermion - ToF distance sensor TMF8801- 2,5m - I2C - DFRobot SEN0430
DFRobot Fermion module with the time-of-flight (ToF) distance sensor TMF8801, which can measure at a proximity range of 2 cm to 10 cm and at a distance range of 10 cm to 250 cm. The device measures with an accuracy of ±5% in both well-lit and dark environments. The sensor measures distance based on the time difference between light pulses. It detects objects regardless of the color, reflectance and texture of the object. The module uses an I2C interface for communication and is powered by 2.7 V to 3.3 V .
ToF TMF8801 distance sensor. Goldpin strip also included.
