sen0562 (waterproof light sensor) minimum high voltage level
Trevor.Woerner 2024-09-21 17:20:47 167 Views2 Replies Can the SEN0562 be driven by a 3v3 device? In other words, is its minimum high voltage level below 3v3?
The datasheet shows that the operating voltage of the module is 5V.Have you tested what values are measured when a 5V powered device goes to drive this module? Is it the same as what you are measuring now when you drive it with a 3.3V device?
yiqing.guan In case anyone stumbles across this and is wondering the same thing… it seems to work at 3v3.
Given that its I2C address is 0x23, the sen0562 would appear to be using the Rohm BH1750 16-bit ambient light sensor. I've tested this device on a Rockchip-based rock-pi-s [https://wiki.radxa.com/RockpiS] running Linux kernel 6.12.3 with CONFIG_BH1750=y enabled. Connecting the red wire of the sen0562 device to the 3v3 line of the rock-pi-s (pin 1 or 17 on header 1) gives values that are higher when exposed to more light, and smaller when covered up.
