Transducer Pressure Sensor
N/A
When submersed in liquid, the Pressure Sensor shall convert the pressure exerted by the liquid into an analog voltage signal that shall represent the liquid level. The pressure sensor shall measure the absolute pressure, and the receiver shall contain a sensor to measure atmospheric pressure to make corrections for changes in the barometric pressure. These corrections to the barometric pressure shall be performed in the Receiver where the local atmospheric pressure is measured and subtracted from the absolute pressure signal. |
Additional Description
N/A The Transmitter shall transmit updated level data and battery condition data once every second. The transmitter shall conserve battery power by ensuring most of its circuitry is powered down and asleep between updates. After being asleep for one second, the Transmitter shall wake up, power up the Pressure Sensor, check the level, check the condition of the battery, and then transmits the new data to the Receiver. When this has been done, the transmitter shall go back to sleep. |
