Hi all. I'm new to this site, my English is not marvelous, so go easy on me . Hope you all understand me.
So here is my problem. I want to create low power water level sensor. Was searching for that kind of sollution on internet but didn't find any.
There are a lot of water level sensors, but most of them are high voltage or high current sollutions.
There is also a huge selection of low power microcontrollers and batteries, so this is not an issue.
Project requirements:
- non-rechargeable 3,6 V battery power supply, was looking for LS 14500
- MCU for data processing, most time it will be in sleep mode, will wake up once every two days or even less
- also have sensor dimensions limitations, height about 10 cm and max. 3 cm width
- lifespan at least 1 year
Sensor will be put in 1 liter tank. Accuracy is not that relevant, i mostly want to know when the tank is empty.
Would love to hear some suggestions and ideas about measuring water level.
