## Description

Module with APDS-9930 for ambient light measurement and proximity detection, ideal for Arduino projects and compatible boards, operates at 3.3V and communicates quickly via I2C, offers up to 16 bit resolution for precise readings, includes programmable threshold interrupt and low power mode for minimal consumption between measurements.
Gesture proximity sensor, ambient light CJMCU9930 APDS 9930, compatible with Arduino and other development boards.
This sensor works at a logic voltage of 3.3V, which is why it is necessary to use a logic level converter if you use 5V microcontrollers.
This sensor can be used to detect light intensity but also proximity to objects (similar to the proximity sensor used by mobile phones).
There is the possibility to put the sensor in the Low Power state for low consumption between measurements.
This sensor works well both in well-lit environments and in dark rooms.
