level sensor available at Tomson Electronics, Kochi, Kerala, India is a
simple and easy to use, and high cost performance, water identification
detection sensor. Working voltage: DC 3-5V, working current: <20mA.
Exposed through a series of parallel wire line mark to measure the water droplets and size to determine water level.
Easy to complete the water to the conversion of the analog signal, the output of the simulation values can be read directly by an Arduino or Raspberry Pi, to achieve the effect of water level alarm.
