## Description

desertcart.com: Taidacent Mini External Sticker Intelligent Non-contact Electronic Water Level Sensor High Low Level Output Liquid Level Sensor Switch for Water Tank Fish Tank

Review: Works great - I purchased 1 and it worked fine. It sinks about 5mA when the sensor is not near water and nearly 0 when it is near water. The instructions gave some nice example circuits for wiring an LED or a microcontroller. I did notice it is possible to have it not quite turn off all the way (it normally conducts until it is near water) if the wall of your water container has some drops on it. From a practical standpoint the implications of that are obviously project specific. For the most part it turns on and off quickly with no time spent in the linear region, straight to saturation.
Review: Seems a bit pricey, but Neat sensors. - Not sure why these are $10 each, seems more like a $2-3 item. They do work and are easy to connect to MCU. I bought a couple different kinds for testing, but my project requires 25 of these sensors. Will go to AliExpress for the rest - it’s cheaper there.

## Features

- The non-contact liquid level sensor is suitable for the outer wall of non-metallic containers without direct contact with the liquid.
- Water tank level sensor will not be corroded by strong acids and alkalis and other corrosive liquids, and will not be affected by scale or other debris.
- The detection is accurate and stable, and the boiling water level can be detected, can be used for water level gauge.
- High stability, high sensitivity non contact liquid level sensor , strong anti-interference ability, free from external electromagnetic interference, special treatment for power frequency interference and common mode interference, to be compatible with 5V power adapters on the market
- Small liquid level sensor: High and low level output mode, suitable for connecting various circuits and product applications.

## Questions & Answers

**Q: Sensor reading is always same as input voltage. Bad sensor? Did I damage it somehow?**
A: If you wired it right, it should not be damaged. But this sensor is sensitive to other materials (not just water). Looks like a capacitive sensor. If I use mine close to a wood, or thick glass, it detects it. On free air, however, it should detect nothing. If you touch it it will detect you too.

**Q: I will be using this with the container that is not clear it’s a gray solid will this still detect through that color**
A: container gray color does not affect the sensor

**Q: I’d like to know if it would work for filling glass bottles conected to a solenoid valve, bottles are filled with a 1/4 steel pipe**
A: you would have to try with your bottle but my experience has been if it is setup properly AND you isolate the valve control with a optoisolator based relay ($2 on this site) you will be ok. I've setup mine to fill my coffee maker when low and shutoff when filled. High level sensor is the failsafe if the flow rate is exceptional. remember that the sensor is 5VDC device and valves are usually higher voltage (12 or more VDC). So again, the sensor can't drive the valve directly!! use a relay

**Q: Can someone recommend a PCB mounted mating connector for this?**
A: A 4 pin pcb header will suffice.
