概要
説明
The ISL29030AIROZ-EVALZ evaluation board is used to evaluate the performance of Renesas' ISL29030A low power ambient light and proximity sensor with intelligent interrupt and sleep modes.
The ISL29030A is an integrated ambient and infrared light-to-digital converter with a built-in IR LED driver and I2C interface (SMBus compatible). This device uses two independent ADCs for concurrently measuring ambient light and proximity in parallel. The flexible interrupt scheme is designed for minimal microcontroller utilization.
