This project primarily consists of four units: Microchip Technology’s SST89E54RDA-40-C-PIE, a sensor unit, an ADC0804 ADC component and the LCD module. Along with detecting an obstacle, its exact ...

In all but the most pedestrian of cases, you really should consider some form of input protection between your sensors and your computational platform. In my “Beginner’s Guide to Sensor Interfacing ...

With just a few components, you can provide a translated signal from industrial and PLD sensors that connects safely to a microcontroller, with the added bonus of supplying 7.5 mA of regulated power.
