is there any pressure sensor 0-cca 10kPa that works on 3V and consumes less than 2mA at the same time. Some sensors are declared to work at 10V and consumes 7mA, is it possible to supply this sensor with 3V and linearly reduce its current consumption to cca 2mA? Did anybody tried this before? I need this sensor to measure water level to about 1m (3-4 feet) deep?
It can be a compensated sensor without internal amplifier as I can add external instrumentation amplifier and mcu.
