Water Pressure Sensor with MCU and RF Transceiver

06/02/2011 5:05 AM

We are developing a Water Pressure Sensor (Measurement) with MCU and RF Transceiver. I found that Freescale Semiconductor's MPXY8300 is almost the one to be applied for this job.

But this MPXY8300 is dedicated for Tire Pressure Monitoring System; it's intended for dry air media.

The question are

1. Is there any similar product as MPXY8300 that can work for Waster Pressure Monitoring?

2. If we want to use MPXY8300 for Water Pressure, is it possible? Or any modification is needed?

Regards,

There is so much else available for water pressure sensing in the marketplace that is seems barely worthwhile. What is special about this newly-proposed sensor, please?

The initial message may not give all detail of its requirement/specification, because the MPXY8300 information is obvious. So, I try to give more info.

It's not a normal Pressure Sensor, but it's low power with MCU (Micro Controller Unit) and RF Transceiver (433 MHz. transmitter and 125kHz receiver for wake up function) which intend to work 10 years without changing battery.

Because of the power supply issue, we need to develop this kind of device. (It is to be use in the Water Utility pipe system where the power supply is not easy to get as the Electric Utilities.)

Check out Sensors magazine and its advertisers for this level of component

Because of your power constrain I would suggest a high impedance sensor. You may find what you really need: a ceramic sensor (thus insensitive to water) with a bridge 10kOhm (thus very low power requirements) at " CiTy Sensors ".

The sensors are small and are used among other applications in water level measurements. As far as I know (I used for other applications their products) prices are quite competitive.

Fix a Flat has a design that sends liquid into an air chamber.
