Hello thanks for reading
Im currently trying to experiment with a device to warn on low pressures for a solar system I'm experimenting with.
Im an engineer but know very little about electronics other than i can construct from drawings, therefore i need a little advice
The circuit i need needs to run off a small lithium battery and give a visual warning as well as a buzzing noise to indicate low pressure at a set point.
The warning needs to be set at about 0.5 bar
I've found a silicon sensor online
any advice about these would be very helpful
link to sensor I'm looking at:
http://www.alibaba.com/product-detail/UPX19-OEM-piezo-silicon-water-pressure_1473391225.html?s=p
i can source the sensor in many different specifications
I'm trying to get the battery to last for as long as possible so maybe some sort of break circuit when pressure is ok (above 0.5 bar) and make circuit when its below triggering small led flash and buzzer
The device needs to be as small as possible, sensor/circuit/battery needs to fit in a housing 40mm by 40mm
Im hoping to get the battery life to 5 years plus
Great-full for any advice
