For and A/C cart for automotive service, customer is looking to measure the liquid level in 3 plastic bottles.
The Cypress kit -022, Liquid Level Sensing works great for water (Er=80). When tried with oil (Er=3) it was ineffective.
Sensing element can be inside the bottle and in contact with the fluid.
Does anyone have a suggestion for oil detection? Needs to be about $4 to replace existing solution. (Load Cell)
IR, NFC, proximity???
Resolution needs to be 2mm or better.
