Sensors

Sensor modules for environmental, motion, distance, light and electrical measurement, spanning multiple platforms rather than one ecosystem. Before choosing, check supply and logic voltage, communication interface (I2C, SPI, UART or analog), measurement range and accuracy — the same physical measurement can be served by sensors with very different electrical requirements, and getting that match right matters more than the headline spec.
