Photoelectric Water Level Sensor For Raspberry Pi And Arduino With Open Collector Output Optical Liquid Level Sensor For Easy Plug And Play Automatic Irrigation Aquariums Gardens And Agriculture Projects

Optical Water Level Sensor for Arduino & Raspberry Pi
✔️ Single-unit optical water level sensor with open-collector output (3.3V/5V)

This photoelectric water level sensor uses optical principles to detect liquid height without moving parts. It’s ideal for automatic irrigation systems, aquariums, gardens, and agricultural setups, and it integrates easily with Arduino or Raspberry Pi via the open-collector output.

✅ Open-collector output compatible with Arduino and Raspberry Pi
✅ DIP switch selects 3.3V or 5V high level logic
✅ No moving parts; low power consumption; corrosion resistance; high temp tolerance
✅ Compact probe with multi-orientation placement (up, down, side, diagonal)
✅ Made for automatic irrigation, aquariums, gardens, and agriculture projects
