Water level sensor for submersible pump

Extra parts needed:
1. Electrical terminals (2x)
2. 3mm x 60mm stainless steel rods (2x)
3. High quality 2x0.5SQMM lamp wire (up to 35m)
4. Heavy duty cable ties (5x)
5. Electrical heat shrink wire shield (4mm in diameter) (optional)
6. Super glue with activator spray
7. High-quality silicon adhesive glue

for the electrical part and board, u can use any kind of mcu or even arduino! for sake of simplicity I used attiny13A and platformIO to program it! the code is Arduino compatible and the circuit is very simple; just two 1uF capacitors and two 100K resistors!

this link contains the code and the circuit schematic!
