1. Introduction
This intelligent rain detection module is mainly intended for automatic wiper control
of security cameras. When installed inside a camera windshield, the module is capable
of sensing precise rainfall status on glass surface of the windshield and feeds back
information(no rain, light rain, moderate rain, or heavy rain) to a host by UART, then
the host can control the wiper get rid of the raindrops on the windshield to ensure a
clear view for the camera in rainy conditions. It features as follows:
⚫Based on optical sensing system, accurately detects rainfall status on glass and
sends information to host via UART;
⚫HALIOS®-SD measurement method, high robustness against strong sunlight;
⚫Less environmental interference and longer service life since the product is
used inside windshields without direct exposure to external natural environment;
⚫Tiny body with a diameter of 12.5±0.15mm, suitable for cameras of all kinds;
⚫CRC-8 check for improving anti-interference ability in communication;
⚫Partial parameters setup can be changed by UART configuration;
⚫Error self-diagnostic, actively sends error status to host via UART;
⚫Optical system self-calibration;
⚫Ambient light detection, providing cameras with more auxiliary parameters;
⚫On-board temperature detection, excellent temperature linearity to ensure
accurate measurements;
⚫Supporting optical sleep mode to extend the service life of the optic
components.
