A simple depth gauge: ten interleaved copper traces up a 40 x 16 mm strip, so the further the water rises the more traces it bridges. The signal pin gives an analog voltage that climbs with immersion depth, from a 3-5V supply. Good for tank levels, plant trays and leak alarms. One tip - power it from a digital pin and switch it on only while reading, because standing voltage in water corrodes the traces fast.

Key features

  • Analog output rises with immersion depth
  • 40 x 16 mm sensing area, 20 x 60 mm board
  • Runs on 3-5V, reads on any analog pin
  • Three pins: S, + and -, plus two M3 mounting holes
  • For tank level, plant trays and leak detection
  • Power it only while reading - constant power corrodes the traces
